JILA Fellow Jun Ye is interviewed for the Buff Innovator Insights Podcast hosted by the CU Boulder Research & Innovation Office. 

In a significant advance toward the future redefinition of the international unit of time, the second, a research team led by the National Institute of Standards and Technology (NIST) has compared three of the world’s leading atomic clocks with record accuracy over both air and optical fiber links.
 

In the first episode of the brand new podcast, Buff Innovator Insights, JILA Fellow Margaret Murnane speaks on her background, her research, and her goal to produce the microscopes of the future. 

Entangled particles have always fascinated physicists, as measuring one entangled particle can result in  a change in another entangled particle, famously dismissed as “spooky action at a distance” by Einstein. By now, physicists understand this strange effect and how to make use of it, for example to increase the sensitivity of measurements. However, entangled states are very fragile, as they can be easily disrupted by decoherence. Researchers have already created entangled states in atoms, photons, electrons and ions, but only recently have studies begun to explore  entanglement in gases of polar molecules. 

When looking within a quantum internet, the Sun Lab is looking at specifically photons. By entangling these photons, scientists tie little quantum knots between them, so they jointly represent the information to be delivered. The photons aren’t just paired off within these quantum knots. They’re connected to hundreds of other photons in a tree-shaped pattern. The robust redundancy of these photons means that scientists can still read the information, even if a few photons are lost.

JILA Fellow Heather Lewandowski has been awarded the 2021 Boulder Faculty Excellence Award. This award was given specifically for Lewandowski's excellence in teaching and pedagogy.

For nearly a century, scientists have worked to unravel the mystery of dark matter—an elusive substance that spreads through the universe and likely makes up much of its mass, but has so far proven impossible to detect in experiments. Now, a team of researchers have used an innovative technique called “quantum squeezing” to dramatically speed up the search for one candidate for dark matter in the lab. 

For the first time, researchers can turn on an electric field to manipulate molecular interactions, get them to cool down further, and start to explore collective physics where all molecules are coupled to each other.

Building on their newfound ability to induce molecules in ultracold gases to interact with each other over long distances, JILA researchers have used an electric “knob” to influence molecular collisions and dramatically raise or lower chemical reaction rates.

Margaret Murnane and Henry Kapteyn, who pioneered technologies for generating coherent X-rays, which helped propel research in dynamic processes in atoms, molecules and materials, have been named fellows of the National Academy of Inventors.

JILA researchers have used a state-of-the-art atomic clock to narrow the search for elusive dark matter, an example of how continual improvements in clocks have value beyond timekeeping.

Konrad Lehnert becomes the 6th JILA Fellow elected as an American Association for the Advancement of Science (AAAS) Fellow by the Council of the AAAS.

JILA fellow Jun Ye has been named Highly Cited Researcher for 2020 by Clarivate Analytics. Ye has been awarded the Highly Cited Researcher in the field of physics every year since 2014.

Follow that electron! JILA researchers have proposed a means of capturing an electron's flight path during ionization, and in doing so, determining the state of the atom at that moment.

When it comes to chemical reactions, shape matters. The Lewandowski Group have studied acetylene and its reactions with propyne and allene to find out how an isomer changes the chemical reaction pathway.

We're in the Second Quantum Revolution, and companies are eager to build and market new technology based on rapid advances in quantum physics. JILA Fellow Heather Lewandowski and her group decided to find out what qualifications these companies were looking for in the new quantum workforce. 

During upconversion photoluminescence in rubrene, four triplet state ions fight it out to release a single high-energy photon. 

A strangely shaped cloud of fermions revealed a record-fast way of cooling atoms for quantum devices.

"Unraveling" cell membrane proteins could help us understand how to build better drugs and treatments for disease.

In the wake of the ongoing coronavirus pandemic, instructors are planning their courses for virtual platforms—a major challenge for laboratory classes. JILA Fellow Heather Lewandowski has gathered some helpful tools for those teaching physics labs in a virtual classroom.
