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

Ye wins 2018 Rabi Award for research on optical lattice atomic clocks
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!

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.

Ana Maria Rey Named NIST Fellow
Published: 08-21-2017

Ana Maria Rey has been appointed a NIST Fellow as of August 21,2017 by the Acting Director of NIST. JILA is a research and training partnership between the University of Colorado and NIST, and Ana Maria is one of the several JILA Fellows who are NIST employees. Ana Maria was named a NIST Fellow in recognition of her world-leading program in quantum theory, her pioneering work in quantum many-body physics, and her continuing powerful collaborations with experimentalists at JILA, at NIST, and across the world.

NIST Fellow is the highest scientific position at NIST, and is limited to no more than 40 of the more than 1,800 scientific employees across the organization who demonstrate unique scientific leadership and innovation. The NIST Director also relies on the NIST Fellows to provide advice and guidance about current and future research directions for the organization. Ana Maria joins Eric Cornell, David Nesbitt, Jun Ye, and Judah Levine as JILA Fellows who are also NIST Fellows.

“It’s a great honor for me,” Ana Maria said. “NIST has been part of my life, my research and my career since I did my PhD thesis work with Charles Clark of NIST. I chose to become a theoretical physicist because I heard (NIST Nobel Laureate) Bill Phillips giving a talk at NIST.”

“Becoming a NIST Fellow is the latest of many well-deserved honors for Ana Maria in her enormously productive scientific career,” said Tom O’Brian, Ana Maria’s NIST supervisor at JILA. “Ana Maria has a huge impact on JILA, NIST, and the international scientific community. She and her group have the unique ability to fully collaborate with experimentalists. They have developed new theory that directly advances experiments such as the world’s best atomic clocks, world-leading programs in ultracold molecules, and world-record entanglement of ions for quantum simulation––among many other accomplishments. Ana Maria is also an exceptional mentor and teacher, preparing her graduate students and postdoctoral researchers for highly productive careers of their own. JILA and NIST are extremely fortunate to have Ana Maria’s leadership.”

Congratulations to Ana Maria.

Leah Dodson Wins 2017 Miller Prize
Published: 07-18-2017

Leah Dodson won the Miller Prize at the 72nd International Symposium on Molecular Spectroscopy, held June 19–23 in Urbana, Illinois. Dodson is an NRC postdoc whose official advisor is Jun Ye, but who primarily works on molecular spectroscopy in the Mathias Weber lab. Her award-winning talk was entitled “Oxalate Formation in Titanium––Carbon Dioxide Anionic Clusters Studied by Infrared Photodissociation Spectroscopy.”

“Leah gave a nice polished presentation with good organization and clarity,” said Ben McCall, Chair of the International Symposium on Molecular Spectroscopy, in a letter to Weber announcing the award. “She clearly outlined the rationale, the experiment, and the results. She was engaged, excited about her project, and good at thinking on the spot.”

Dodson’s project featured in her talk was the investigation of catalysts in model systems. Specifically, she studied the possible use of titanium dioxide (TiO2) as a catalyst to break carbon-oxygen (C–O) bonds in carbon dioxide (CO2) produced in a factory. Breaking C–O bonds in CO2 is a key step in turning this greenhouse gas back into usable fuel––and keeping it out of the atmosphere. Dodson’s experiment worked surprisingly well. In the experiment, TiO2 anions effectively broke COmolecules, forming metal carbonyl in the process. This experiment was the basis for her symposium talk, which resulted in the Miller Prize.

As a Miller Prize winner, Dodson has been invited to present a 15-min talk in one of the plenary sessions in the June 2018 symposium. Dodson will also serve as a judge in the 2018 Miller Prize competition. In addition, she and her coauthors have been invited to submit an article based on her talk at this year’s symposium to the Journal of Molecular Spectroscopy. 

Bryce Bjork Awarded 2017 Rao Prize
Published: 07-17-2017

Bryce Bjork’s talk entitled “Direct Measurement of OD+CO-> cis-DOCO, trans-DOCO, and D+CO2 Branching Kinetics using Time-Resolved Frequency Comb Spectroscopy” was selected by a panel of judges at the International Symposium on Molecular Spectroscopy as one of three winners of the 2017 Rao Prize. The prize will be presented to Bjork at the June 2018 Symposium.

In addition, Bjork was asked to serve as a judge in the 2018 Rao Prize competition. If he is able to attend next year’s Symposium, his registration fee will be waived and he will receive an up-to-six nights’ stay at the four-bedroom suite rate.

“There were many superb talks, but yours was exceptional,” said Gary Douberly, Chair of the 2017 Rao Prize Committee, in a recent letter to Bjork informing him of his selection. “We hope that this prize represents the beginning of what we expect will be a distinguished career in science.”

Rao Prize winners and their co-authors are invited to submit articles based on their talks to the Journal of Molecular Spectroscopy. When published, the article will appear in the journal with a caption linking the paper with the symposium talk that won the Rao Prize.

“The prize is given to graduate students,” said Jun Ye, Bjork’s advisor at JILA.  “But, it usually signifies the beginning point of a young spectacular scientific career in the field of molecular spectroscopy.” 

NPR’s Eric Westervelt Talks with Carl Wieman about His New Book
Published: 06-13-2017

NPR’s education reporter Eric Westervelt is excited about Nobel Laureate Carl Wieman’s passion for transforming how undergraduate science courses are taught. On June 7, 2017, Westervelt talked with Wieman about his new book Improving How Universities Teach Science: Lessons from the Science Education Initiative, which was published by Harvard University Press in May of 2017.

Wieman’s message is that universities should do away with lectures in undergraduate science courses and replace them with active learning methods. Instruction based on active learning substantially improves understanding and retention of complicated material. Plus, students attend more classes and get more out of their classroom experiences. Armed with data to prove that he’s right about the effectiveness of active learning methods, Wieman is determined to convince universities across the nation to give up on the lecture method of teaching science to undergraduates.

The lecture system “grew up haphazardly,” Wieman explained during the interview. “Really it grew before the printing press was invented, and the structures––like the lecture––were how to transmit information to people who didn’t have books.”

Wieman said his research showed that lectures actually circumvent the way the brain processes and learns new information. During a lecture, information just flows by and students typically retain only about 10% of what they hear. And, to make matters worse, many students these days are busy with cell phone apps as the information flies by. Another problem is that universities often value faculty research accomplishments far more than teaching skills.

Westervelt first spoke with Wieman on NPR about improving science teaching in universities on April 14, 2016. That program was entitled “A Nobel Laureate’s Education Plea: Revolutionize Teaching,” In that interview, Westervelt said that Wieman believed that, “the college lecture is the educational equivalent of bloodletting, one long overdue for revision.”

Carl Wieman began his research on undergraduate science education while a Professor of Physics at the University of Colorado Boulder and a Fellow of JILA. Wieman joined the University of British Columbia in 2007 and moved to Stanford University in 2013, where he is Professor of Physics and Professor of the Graduate School of Education. Wieman is a Fellow Adjoint of JILA.
