Department of Defense Awards Konrad Lehnert Prestigious Vannevar Bush Faculty Fellowship
Published: 05-12-2020

JILA Fellow Konrad Lehnert has been awarded the Vannevar Bush Faculty Fellowship, the Department of Defense’s most prestigious single-investigator award. With up to $3 million in funding, the VBFF is a five-year fellowship which supports basic research with the potential for transformative impact.

Formerly known as the National Security Science and Engineering Faculty Fellowship, the program changed its name in 2016 to commemorate the late Dr. Vannevar Bush, who was the director of the Office of Scientific Research and Development during WWII and the author of “Science, The Endless Frontier.” Bush was an ardent advocate for basic research who made innovative contributions to the national security. JILA Fellow Margaret Murnane won this Fellowship in its inaugural competition in 2008.

Lehnert’s proposed research aims to understand and quantum control phonons, the quantum packets of sound. While physicists have explored quantum control of light for new computers and electronics, sound waves behave quite differently than light waves, and in ways that could advance quantum information science.  Sound is a hundred thousand times slower than light, so it can be used to create multiple modes in a smaller cavity—which could be used to store and process information on a smaller chip. Lehnert’s research group explores phonons’ potential for quantum computing, information processing, information security, and sensing.

Congratulations to Dr. Lehnert!

JILA Fellow Adam Kaufman wins Office of Naval Research Young Investigator Award
Published: 04-08-2020

The Office of Naval Research has awarded JILA Fellow Adam Kaufman one of its prestigious 2020 Young Investigator Awards. The ONR program rewards early career scientists “who show exceptional promise for doing creative research”—and Kaufman is a most deserving recipient.

“This selection recognizes both his past accomplishments and his vision for developing optical tweezer arrays for demonstrating useful quantum computing,” said Tom Perkins, acting NIST Quantum Physics Division Chief. “Congratulations to Adam for his selection as a ONR 2020 Young Investigator.”

"JILA is delighted that Adam's accomplishments and exciting future project plans are being recognized by this award,” said JILA Chair Andreas Becker. “Congratulations to Adam."

Kaufman and his team specialize in optical tweezers—tightly focused beams of light which manipulate and precisely control individual atoms. Optical tweezers have transformed quantum science research, and the Kaufman Group at JILA has explored new frontiers with this technology.

“A key development that came out of our group was to apply this technology, for the first time, to an alkaline-earth atom, like strontium or ytterbium—atoms which are famous for their use in atomic clocks and quantum science broadly. We focus on how to combine these favorable properties of alkaline-earth atoms with the capabilities afforded by optical tweezer technology to, for instance, build large quantum entangled systems,” Kaufman said.

The ONR Young Investigator award includes $510,000 over a three-year period. Kaufman plans to use quantum information entangling protocols to assemble entangled states that could impact enhanced atomic clock architectures. This research could extend beyond atomic clocks, including quantum computing and many-body physics.

JILA Fellows Margaret Murnane and Henry Kapteyn Win the Benjamin Franklin Medal for Physics
Published: 01-27-2020

A husband-and-wife team at the forefront of laser science at the University of Colorado Boulder has followed in the footsteps of the Curies, winning a prestigious Benjamin Franklin Medal.

The Franklin Institute announced today that Henry Kapteyn and Margaret Murnane would receive this year’s medal in physics—one of several awards handed out annually by the center named after the scientist and founding father.

Kapteyn and Murnane are fellows at JILA, a joint research institute between CU Boulder and the National Institute for Standards and Technology (NIST). They have pioneered new advancements in X-ray lasers, devices that shoot out incredibly fast pulses of X-ray radiation.

The researchers, also professors in the Department of Physics, are only the third married couple to receive a Benjamin Franklin Medal. The first were Marie and Pierre Curie who took home the prize for chemistry in 1909.

“We are quite excited and humbled to be so recognized by the Franklin Institute,” Kapteyn said. “Margaret and I have been exploring science together for many years now, so it is especially delightful to be following the path of the Curies—a personal inspiration for us—in being recognized by such a longstanding, prestigious organization.”

“Margaret Murnane and Henry Kapteyn are highly-acclaimed, international leaders in laser science,” said John Cumalat, chair of physics at CU Boulder. “The Department of Physics takes great pride in their recognition as 2020 Franklin Institute Award Winners. They are remarkable scientists, professors and mentors of our students.”

Setting records

When Kapteyn and Murnane first earned their PhDs from the University of California, Berkeley, in the late 1980s, most X-ray lasers could fill a building the size of a warehouse. They wanted to go smaller and less expensive.

The researchers, who joined the CU Boulder faculty in 1999, developed the first “tabletop” X-ray laser in research spanning more than 20 years. They’ve since pushed the field even further. Kapteyn and Murnane’s latest designs can send out busts of light at speeds of roughly a billionth of a billionth of a second—and with more precise control than any other lab has been able to achieve.

The Franklin Institute honored Kapteyn and Murnane for making these devices “accessible to a new generation of researchers and applications in fields ranging from electronics to medicine.”

To do just that, the physicists founded the company KMLabs in the 1990s. For their efforts, they received a Colorado Governor’s Award for High-Impact Research in 2018.  

“JILA is excited that Margaret and Henry are again recognized for their decades-long advancement of ultrafast lasers and laser-based X-ray investigation of materials,” said Thomas Perkins, former chair of JILA. “In additional to their scholarly publications, they have educated scores of students and postdocs that continue to push the frontier. Moreover, they founded KMLabs that facilities a broader user base of accessing their advancements and enhance our regional economy.”

New feats of imaging

Kapteyn and Murnane have also dug deep into what is possible with these new, fast devices.

They explained that their tools allow scientists to view phenomena that were previously too tiny and quick-moving to observe. These lasers can, for example, spy on the energy flowing through ultrathin semiconductors, follow chemical reactions in real time and probe the behavior of animal neurons.

In 2016, the duo helped to launch the Science and Technology Center on Real-Time Functional Imaging (STROBE), a $24 million initiative funded by the National Science Foundation. Among other goals, this partnership with several other universities seeks to develop “the microscopes of tomorrow”. Such devices could one day combine a wide range of imaging approaches into a single device, allowing scientists to observe phenomena that have been beyond their reach to date. Murnane currently directs STROBE, and Kapteyn is its Knowledge Transfer Director.

Kapteyn and Murnane join six other researchers receiving Benjamin Franklin Medals in various fields in 2020. They will officially receive their awards at a gala ceremony in Philadelphia in April.

Both Kapteyn and Murnane are fellows of the American Association for the Advancement of Science, the Optical Society of America, the American Physical Society, and members of the U.S. National Academy of Sciences. Murnane was named a MacArthur “Genius” Fellow in 2000. Originally from Limerick, Ireland, she received the St. Patrick’s Day Science Medal for Academia from the Science Foundation Ireland.

JILA team demonstrates model system for distribution of more accurate time signals
Published: 10-21-2019

JILA physicists and collaborators have demonstrated the first next-generation "time scale" - a system that incorporates data from multiple atomic clocks to produce a single highly accurate timekeeping signal for distribution. The JILA time scale outperforms the best existing hubs for disseminating official time worldwide and offers the possibility of providing more accurate time to millions of customers such as financial markets and computer and phone networks.

The novel time scale architecture combines a super-reliable, advanced atomic clock with an ultrastable device for storing time signals and is a "blueprint for the upgrade of time scales worldwide," as described in the journal Physical Review Letters.

JILA is jointly operated by the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.

"I think this new time scale demonstration will be very important for the redefinition of time in the future," said Jun Ye, NIST/JILA fellow and project leader.

The recent redefinition of the International System of Units (SI) did not update the way time is measured. The standard unit of time, the second, has been based on properties of the cesium atom since 1967. In the coming years, the international scientific community is expected to redefine the second, selecting a new atom as the basis for standard atomic clocks and official timekeeping.

To prepare for this change, researchers need to upgrade systems for distributing time. NIST operates the nation's civilian time scales, arrays of hydrogen masers - microwave versions of lasers - that provide reliable oscillating signals to maintain stable "ticking" for the official U.S. civilian time of day, which is linked to international time (coordinated universal time or UTC). Two atomic clocks based on the cesium standard, called NIST-F1 and NIST-F2, are used to calibrate and ensure the accuracy of the time scales. Like next-generation atomic clocks, JILA's experimental time scale operates entirely at optical frequencies, which are much higher than the microwave frequencies of cesium time standards. Optical frequencies divide time into smaller units and thus can offer greater accuracy. 

Efforts to incorporate the latest optical atomic clocks into older microwave time scales have run into limits on long-term stability, due to the inherent properties of masers and the fluctuations associated with linking them to experimental clocks that operate intermittently.

The JILA team solved these problems by optimizing a more stable type of oscillator and tightly controlling operating conditions such as temperature so their highly stable and precise strontium lattice clock can be operated regularly on demand.

The oscillator is formed by a laser beam aimed into a hollow cavity made of a single crystal of silicon, inside of which laser light of a specific color, or frequency, bounces back and forth regularly for a long time, like a metronome. These devices have been around for years, but a long-term JILA collaboration with Physikalisch-Technische Bundesanstalt (PTB), the German national metrology institute, came up with a new way of building them, greatly improving the stability of the light. Recently, the JILA team further boosted the long-term stability of their cavity, which is 21 centimeters long and operates at cryogenic temperatures of 124 K (minus 149.15 C), by using superpolished optics and improved heat control, among other tweaks.

In the JILA time scale, an optical frequency comb (a ruler for light) transfers the stable optical signal from this cavity to another, very stable laser that is shined on the clock's atoms and synchronizes the light's frequency with their ticking. Two additional lasers are stabilized to independent cavities. The multiple lasers and cavities provide redundancy in case anything malfunctions.

The stability of the oscillator was compared continuously to that of the NIST microwave time scale by a preexisting underground fiber-optic link between JILA, on the university's campus, and NIST, a mile or so away. Over a month of measurements, the frequency stability of the optical oscillator consistently surpassed that of the masers in the microwave time scale.

The experimental results show that the JILA time scale architecture outperforms microwave time scales, even when the masers are calibrated by next-generation atomic clocks. The team's analysis indicates that by running the JILA optical clock 50% of the time, the all-optical time scale could reach a stability level about 10 times better than the standard microwave time scale, or 1x10-17, after a few months of averaging.

A further practical advantage is that the oscillator frequency can be predicted using conventional microwave analysis techniques, enabling the team to estimate a timing error of only 48 ± 94 picoseconds (trillionths of a second) after 34 days of operation.

Additional technical upgrades are planned, including automation that should allow the clock to be operated more than 50% of the time. Researchers also plan to incorporate the optical time scale signal into the NIST time scale using the underground fiber network.

Co-authors of the paper include researchers from the NIST Time and Frequency Division as well as from PTB.

The work is supported by NIST, the Defense Advanced Research Projects Agency, the Air Force Office of Scientific Research, the National Science Foundation, PTB, and the Cluster of Excellence (Quantum Frontiers).

Australian fellowship named for late JILA Fellow Deborah Jin
Published: 07-26-2019

JILA Fellow Deborah Jin’s research was literally the coolest. She created the first fermionic condensate and the first quantum degenerate molecular gases, expanding our knowledge of how atomic and molecular behavior changes at ultracold temperatures. Jin was not only a prominent physicist, she was a role model and mentor for young scientists, particularly women.

“She was a physics giant. Her research on fermionic gases helped us advance our field in an impressive way,” said JILA Fellow Ana Maria Rey, who worked with Jin. “Besides being one of the most prominent physicists in our field, she was a caring mother, a fantastic wife and a supportive colleague and friend."

Although Jin passed away in 2016, her research continues to influence physicists around the world. The Australian Research Council Centre of Excellence for Engineered Quantum Systems (EQUS) is now offering Deborah Jin Fellowships to two early career female scientists.

“This prestigious fellowship is a great testimony to Debbie’s continuing international impact in research and training,” JILA Fellow Tom O’Brian said.

EQUS is Australia’s national quantum research and development initiative, similar to the United States' National Quantum Initiative or Europe’s Quantum Flagship Initiative. The Deborah Jin Fellowships are three-year appointments at either the University of Queensland, University of Sydney, Macquarie University and University of Western Australia. Applications are due August 5, 2019 at 8:00 AM AEST.

JILA's Ana Maria Rey wins Blavatnik Award
Published: 06-26-2019

The Blavatnik Family Foundation and the New York Academy of Sciences named theoretical physicist and JILA Fellow Ana Maria Rey one of three Laureates for the Blavatnik National Awards for Young Scientists. Each year these awards honor three scientists in life sciences, physical sciences and engineering, and chemistry. The other caveat: all laureates are 42 years old or younger.

“We like to think of them as our young Nobels,” Brooke Grindlinger, chief scientific officer of scientific programs and Blavatnik Awards at the academy told the Boulder Daily Camera. 

Nominated by 169 research institutions from across 44 states, the Blavatnik National Awards received 343 nominees – the largest pool of nominees ever received by the program. For the first time in the awards' 13-year history, all of the laureates are women; as a U.S. citizen who is a native Colombian, Rey is the first Hispanic woman to win this award.

"It is such a huge honor for me to receive this recognition. I could not believe it was given to me," Rey said. "I am really grateful."

“These three women are leading scientists and inventive trailblazers with stellar accomplishments in their respective fields,” said Len Blavatnik, founder and chairman of Access Industries, head of the Blavatnik Family Foundation and member of the President’s Council of the New York Academy of Sciences. “Their groundbreaking research leads the way for future discoveries that will improve the world and benefit humankind. It’s exciting to see these three brilliant scientists chosen as the 2019 Blavatnik National Laureates.”

Rey said she would be honored to be seen as a role model for other young women pursuing physics.

"In my point of view, having role models to inspire women is key. It is very important for women to realize that to have a scientific career it is not incompatible with having a family. Facilitating ways that help women to be a successful scientists and mothers at the same time is crucial," she said. Rey added that she was fortunate to have some great women role models in her early career, including the late Deborah Jin, a fellow JILA physicist.

"She was a physics giant. Her research on fermionic gases helped us advance our field in an impressive way. Besides being one of the most prominent physicists in our field, she was a caring mother, a fantastic wife and a supportive colleague and friend," Rey said.

Rey is a top young theorist in quantum information science and technology (QIST) and atomic, molecular and optical (AMO) physics. Her pioneering work has earned her a MacArthur Fellow Award in 2013 and an American Physical Society Fellow Award in 2015, among many other scientific awards and honors. Rey's theories on atomic collisions led to the development of the world's most accurate atomic clock. That clock is in use at JILA and has been critical in experiments across research groups at the organization.

In addition to being a JILA Fellow, Rey is a Professor Adjoint of Physics at the University of Colorado, and a Fellow of the National Institute of Standards and Technology (NIST), that partners with the University of Colorado to form JILA. Rey is also a leading member of the University of Colorado CUbit Quantum Initiative.

“JILA is thrilled to congratulate Ana Maria for her selection as the Blavatnik National Laureate Award in Physical Sciences & Engineering.  We also thank the Blavatnik Family Foundation for celebrating the successes of young scientists and engineers in the US and worldwide,” said JILA Fellow and Chair Thomas Perkins.

All Blavatnik National laureates and finalists are invited to the Blavatnik National Awards ceremony at the American Museum of Natural History in New York in September. The award comes with an unrestricted $250,000 prize for each winner. Rey says she doesn't have an immediate plans for the winnings, but she couldn't have achieved this honor without her colleagues at JILA, NIST and the University of Colorado Boulder.

"All my research has been inspired by a close collaboration with experimental groups. In particular, the work done at Jun Ye's, James Thompson's and John Bollinger's labs have been the driving force for my research," Rey said. "Also all the successful developments in my group have been possible thanks to the fantastic group of postdocs and graduate students who have worked very hard to accomplish our research goals. They are responsible for all the milestones achieved in my group. I owe all of them so much. I am really grateful and hope that they consider this award as a recognition to their work."

Marit Fiechter wins SPIN prize for best undergraduate physics thesis
Published: 04-17-2019

One of JILA’s former students was awarded high honors at Netherland’s Physical Society’s annual FYSICA conference this April. Marit Fiechter, an undergraduate student at the University of Groningen in the Netherlands, won the Students of Physics In the Netherlands (SPIN) prize for her bachelor’s project, which included a 500 Euro cash prize from the Dutch Society of Physics.

Most undergraduate students in the Netherlands complete a three-month project at the end of his or her degree. Fiechter’s prize-winning thesis on narrow-line cooling of yttrium monoxide grew out of her work in Jun Ye’s lab at JILA. She says JILA’s collaborative spirit not only helped her research, it helped her grow as a scientist.

“I'm very grateful Jun gave me the opportunity to join his group; I really enjoyed my time at JILA,” she said in an email. “Not only did I like the project, I also got along with my coworkers (Ian Finneran, Yewei Wu and Shiqian Ding) really well. They are the reason I've learned as much as I have now, by always answering my questions and then enthusiastically explaining even more!”

She added, “I feel like I was surrounded by talented and hard-working people, who are eager to push their experiment forward while at the same time not stressing out about it.”

Fiechter will start her master’s degree in physics at ETH Zürich this September.

Perkins and Lehnert Awarded Department of Commerce Medals
Published: 09-26-2018

26th September 2018 — JILA Fellows Dr. Tom Perkins and Dr. Konrad Lehnert both received medals from the Department of Commerce last night at the Ronald Reagan Amphitheater in Washington, D.C.

Dr. Perkins received the Gold Medal, which is the highest honorary award given by the United States Department of Commerce, or DOC. Perkins was recognized for creating the world’s best atomic force microscope tailored to biological measurements. This device can “grab” onto biological molecules, such as proteins, and measure the tiny forces involved in their folding and unfolding.

Perkins was also recognized for using this technology to study the structure and dynamics of key membrane proteins, which are proteins that control the exchange of chemicals into and out of cells. His techniques revealed the structure and dynamics of these proteins in ten times greater detail than previously possible. This research will lead to better understanding, and subsequently diagnosis and treatment, of the diseases developed through protein misfoldings, such as Alzheimer’s, Parkinson’s, and cystic fibrosis.

 “I am honored to receive this award,” said Perkins. “It reflects a decade of efforts by my students and post-docs as we sequentially addressed a set of metrological limitations to bioAFM, including a key advance by an undergraduate. We then successfully demonstrated our metrological improvements by resolving a multitude of hidden dynamics of bacteriorhodopsin, a result that biologist and biochemists cared about.”

Dr. Lehnert received the Silver Medal as part of a team of NIST scientists building the components of a quantum communications network. In addition to Lehnert, the team included Dr. Jose Aumentado, Dr. Raymond Simmonds and Dr. John Teufel. Aumentado, Simmonds and Teuful are scientists in the Applied Physics Division of the National Institute of Standards and Technology in Boulder, CO.

The team was recognized for the first realization of the complex components needed for future quantum networks. Quantum networks, or the ability to connect multiple quantum nodes, will advance quantum computing and the rapid, secure exchange of quantum information. The components realized by the team include techniques to store, exchange, transmit, amplify, and readout quantum information using quantum-based superconducting circuits and quantum-controlled micromechanical resonators. The team’s accomplishments represent multiple first and best advances in technologies for quantum networks.

“It was exhilarating to get out in front of this highly competitive new research area,” said Lehnert. “By working together, John, Ray, Jose and I were able to quickly make great progress.”

The awarding of DOC gold and silver medals is an annual traditional established in 1949. The awards are presented to individuals, groups, or organizations in the Department of Commerce for extraordinary, noble, or prestigious contributions.

Previous recipients of DOC awards include 14 JILA Fellows. The most recent JILA Fellow awardee was Ralph Jimenez, who was part of a NIST team awarded the Gold Medal in 2017 for developing tools to create stop-action X-ray measurements of molecules. One of the earliest JILA Fellow awardees was Jan Hall, who received the Gold Medal individually in 1969, and again as part of a team in 1974 and 2002. 

Jun Ye Stars in Feature Film
Published: 08-22-2018

JILA Jun Ye hit the big screen this summer as he debuted in the feature-length documentary, “The Most Unknown”.

“The Most Unknown” brings together nine scientists from across the globe, all of whom are using science to answer deep philosophical questions, such as how did life begin, and what is time? The scientists are brought together, (“blind-date style,” as the New Yorker’s review accurately describes it) to discuss how their work from various fields might overlap.  

According to a New York Times review, “‘The Most Unknown’ works best as inspiration to delve deeper into these disciplines, and as a celebration of science.”

The full 85-minute film was produced by Motherboard, Vice’s media tech-culture channel, and directed by Emmy-nominated and Peabody Award-winning filmmaker Ian Cheney and advised by world-renowned filmmaker Werner Herzog. The film was made possible by a grant from Science Sandbox, a Simons Foundation initiative dedicated to engaging everyone with the process of science.

The film was first released on 18 May 2018 in only select U.S. theatres. As of August, the film is streaming on Netflix.

A live screening with special guests will be held at the University of Colorado Boulder on Monday, October 1st

Published: 02-22-2018

JILA Fellow Jun Ye was named the 2018 winner of the I. I. Rabi Award by the IEEE Frequency Control Symposium. Ye was recognized “for the development of stabile, reproducible, and accurate atomic clocks based on optical lattices, and the use of those clocks to probe fundamental atomic interactions and quantum many-body systems.”

The award recognizes Ye’s sustained leadership in perfecting optical lattice atomic clocks as the most accurate and precise timekeepers in the world, and Ye’s continual pioneering of new physics, such as his recent first-in-the-world Fermi degenerate gas atomic clock using quantum many-body physical principles to dramatically improve clock accuracy and stability.

The IEEE Frequency Control Symposium is the world’s largest and most important scientific society dealing with atomic timekeeping and related topics. The Rabi Award is the Symposium’s highest award for scientific research in atomic timekeeping. Award namesake Isidor Rabi was the 1944 Nobel Physics Laureate for his invention of the resonance technique in molecular beams. In 1945, Rabi was the first to suggest this method could be used to make atomic clocks, and indeed Rabi’s method was adopted for the best atomic clocks for several decades. More recently, Ye and other scientists perfected the new and more precise method of optical lattice atomic clocks.

Previous Rabi Award winners at JILA have included JILA Fellows Jan Hall and Judah Levine.

The award will be formally presented to Ye at the International Frequency Control Symposium in Squaw Creek, CA, May 21-24, 2018.

Congratulations to Jun!

Tom Perkins Wins 2017 Governor’s Award
Published: 08-28-2017

Fellow Tom Perkins has won a 2017 Governor’s Award for High-Impact Research. Perkins will receive the award from Governor John Hickenlooper at an event sponsored by the CO-LABS consortium at the Denver Museum of Nature and Science on October 5, 2017. This year’s ninth annual event will honor Colorado’s top scientists and engineers for projects having a significant impact on society.

“The projects in this year’s CO-LABS High-Impact Awards spotlight what makes Colorado a leader in innovation,” said Governor John Hickenlooper. “It’s terrific to see research advance its partnerships with the private sector. I congratulate the scientific teams for their groundbreaking work and am excited to see the mark they will leave on our state and society as a whole.”

For his part, Perkins said, “I’m delighted to see the Governor and CO-LABS celebrating the diversity of excellent science in Colorado.”

Perkins is being recognized for work described as New twists in the molecules of life. In a decade long project, Perkins developed powerful new tools to measure and study individual biomolecules. He then partnered with the biotech industry to develop tools to improve the measurement and understanding of the structure and function of single proteins and nucleic acids, which play key roles in the biophysics and biochemistry of life. Amazingly, Perkins’ new tools can probe these key biomolecules in real time and under real world conditions.

Starting with an ordinary atomic-force microscope (AFM), Perkins painstakingly modified the AFM cantilevers to make the world’s most precise measurements of the structural components of individual proteins and nucleic acids. Today, he watches these large, complex molecules fold and unfold as they perform normal biological functions. He accomplishes all this in the wet, warm environment of living cells. His new AFM technology can completely analyze the folding and unfolding of a biomolecule in the laboratory in 2–3 days. Without the new AFM technology, this process used to take months of work.

As part of his effort to create better instruments for studying biomolecules, Perkins worked with instrument makers and pharmaceutical/biotech companies to apply his unique AFM technology to making ultraprecise measurements of the real-time folding and unfolding of individual biomolecules. These collaborative experiments are expected to impact medical diagnostics and treatments as well as speeding up the progress of fundamental biomedical and biological research.

Perkins has transferred his new technology through invents and patents, widely cited scientific publications, direct collaborations with industry, and by training young scientists who have built upon his work at AFM and biotech companies.
