JILA graduate student Alexander Aeppli is one of a team of researchers working on the world’s most precise clocks. In the laboratory of JILA and NIST Fellow Jun Ye, Aeppli focuses on improving the strontium atomic clock using powerful ultrastable lasers. “The laser drives an electronic transition in strontium,” Aeppli explained. “And we want to make sure the transition within the strontium is exact.” Before the transition occurs, the strontium atoms are trapped within an optical lattice inside the clock. Once trapped, the strontium atoms can transition when exposed to a particular color (or frequency) of light, and the researchers, like Aeppli, measure this transition frequency as a form of timekeeping. The frequency can then be used as the precise standard of time worldwide.  

JILA's Postdoc Group, an internal organization supporting postdoctoral researchers within JILA, held a career panel titled: "Insights for Applying for Faculty Positions as a Postdoctoral Researcher." The panel featured three JILA Fellows: Margaret Murnane, Shuo Sun, and Graeme Smith, and J. Curtis Beimborn II, the Director of the W.M. Keck Laboratory at JILA, who recently accepted a faculty position on the East Coast. 

Former JILA postdoctoral researcher William “Bill” Peters recently passed away on May 29th after experiencing sudden cardiac arrest while playing soccer with his daughter. Peters was part of JILA Fellows Henry Kapteyn’s and Margaret Murnane’s research group within JILA. Before this position, Peters completed his Ph.D. in physical chemistry at the University of Colorado Boulder in 2013. After completing his postdoc at JILA in 2021, Peters became an optical engineer at Lockheed Martin, working on cutting-edge technological systems. 

His family is holding services this week in Colorado Springs and asks anyone interested in attending to contact Bill’s sister Rebecca Peters, for more information.

This research suggests huge implications for the future of disease diagnosis and prevention. 

JILA graduate student Tyler McMaken has been awarded an honorable mention by the Gravity Research Foundation for his essay in their annual essay competition. Each year, the Gravity Research Foundation opens a competition that awards five essays encouraging discussion and thought on gravitation. Essays must be less than 10 pages and convey science in more accessible and engaging language than in a journal publication. 

Election to the National Academy of Sciences (NAS) is one of the highest honors that can be bestowed upon a scientist in the United States, and it is a mark of recognition for exceptional scientific achievement. This achievement has now been bestowed on JILA and NIST Fellow, along with the University of Colorado Boulder physics professor Ana Maria Rey, as she was inducted into the NAS in 2023. 

University of Colorado Boulder physics professor Jose D'Incao is the newest researcher to become an Associate Fellow of JILA. As D'Incao's research focuses on ultracold quantum physics, he has often collaborated with other JILA Fellows, like Ana Maria Rey, Eric Cornell, and Jun Ye. Now as a Fellow himself, D'Incao will fit right in with the majority of JILA's Fellows who focus on quantum science.

While many JILA alumni go onto have more traditional careers such as in quantum industry, other career paths that might not be as well-known offer some unique benefits. One of these career paths is in medical physics research.  Medical physics is an important and rapidly growing field that is dedicated to the application of physics principles and techniques to medicine and healthcare. Medical physicists are experts in the use of radiation and other technologies to diagnose and treat disease, and they play a vital role in ensuring the safety and effectiveness of medical procedures. They also research and develop the next generation of tools for diagnostic imaging and radiation therapy. For JILA alumni Liz Shanblatt, a Staff Scientist and Collaboration Manager at Siemens Healthineers, medical physics became an interest only as she was nearing graduation and starting to look for jobs.

Heidi Shyu, undersecretary of defense for research and engineering at the U.S. Department of Defense, visited JILA and the University of Colorado Boulder on Monday to glimpse the future of cutting-edge research.

From the university’s proximity to national laboratories and quantum-intensive companies to the high volume of pioneering alumni, CU Boulder has long been a leader in the quantum space. This legacy has led to a push in innovation and technology, including as it pertains to national security—a goal also shared by Shyu and the Department of Defense.

JILA and NIST Fellows Jun Ye and David Nesbitt, along with their respective teams, have recently been highlighted in the latest issue of the SPIE Photonics West Show Daily, a publication from SPIE. This highlight focuses on the recent advancements in the frequency comb breathalyzer apparatus that the researchers have built and tested, which looks at diagnosing COVID-19 and other diseases.

Every year the National Institute of Standards and Technology (NIST) and the Department of Commerce (DOC) grant honor awards in the form of Gold, Silver, and Bronze Medals. According to the DOC website: “the Gold and Silver Medals are the highest and second highest honor granted by the Secretary for distinguished and exceptional performance.” Two of JILA’s Fellows, Jun Ye, and Judah Levine, have been awarded these medals.

JILA (a world-leading physics research institute set up by NIST and the University of Colorado Boulder) is part of a multi-university research group that will build quantum-based tools for space-based Earth sensing.  NASA expects to award a $15 million grant for five years to the group of universities. This cohort includes researchers from the University of Texas at Austin, JILA, the University of Colorado Boulder (CU), the University of California Santa Barbara (USCB), the California Institute of Technology (Caltech), and the U.S. National Institute for Standards and Technology (NIST). “The award establishes the Quantum Pathways Institute, supported by a NASA STRI (Space Technology Research Institute), led by Prof. Srinivas Bettadpur of the University of Texas at Austin, Texas, with CU and UCSB as collaborating institutions,” explained Dana Anderson, a JILA Fellow and CU Boulder professor who is involved in the project. The Quantum Pathways Institute is the first of its kind, as it strives to translate the capabilities of quantum physics into usable devices called “Quantum 2.0.” Besides these developments, the Institute will offer educational training for graduate students and postdocs in quantum theory and quantum experimentation.
