JILA News

Walk down to the basement labs of JILA and you're sure to find something interesting. From atomic clocks to biophysics, researchers are hard at work advancing scientific and technological frontiers. One of these researchers is graduate student Dhruv Kedar. Kedar works in JILA and NIST Fellow Jun Ye's lab, focusing on laser development for a range of applications including optical atomic clocks and optical timescales. “We're really just trying to make the world's best lasers as part of the atomic clock,” explained Kedar. “We do a good job of isolating out any sort of environmental effects so the atomic frequency of the clock doesn't change but gets more precise.” As optical atomic clocks use a series of lasers to control and measure the quantum state evolution inside an atom, which will redefine the SI unit of Second in the foreseeable future, improving the lasers to be themselves free of environmental noise is an important task. 

How does a scientist become interested in quantum physics? For Ana Maria Rey, both a JILA and NIST Fellow, the answer involves a rich and complicated journey. Quantum Systems Accelerator, a National QIS Research Center funded by the United States Department of Energy Office of Science, featured Rey in a new article series in honor of Hispanic Heritage Month. In this article, Rey shares her story and her current research. 

Adam Kaufman — a JILA Fellow, NIST (National Institute of Standards and Technology) Physicist, and University of Colorado Boulder Professor — has been awarded the American Physical Society's (APS) 2023 I.I. Rabi Prize in Atomic, Molecular, and Optical (AMO) physics.

Many researchers at JILA feel honored to work with several big-name scientists within a specialized field of physics. One of these is graduate student Hannalore Gerling-Dunsmore, who is mentored by JILA Fellow Mitch Begelman and Fellow Adjoint Phil Armitage. Studying with these two well-known physicists, Gerling-Dunsmore's work focuses on accretion disk survival, or the conditions needed for the accretion disks of the supermassive black holes at the centers of galaxies      to survive gravitational instability. Her research, along with the support of her advisors, has helped award Gerling-Dunsmore with a prestigious pre-doctoral fellowship at the Center for Computational Astrophysics (CCA). This fellowship is sponsored by the Simons Foundation in New York City. According to Gerling-Dunsmore, the Simons foundation funds: "science that is especially computational in nature and often does not      get a lot of funding from the U.S. government." This funding allows researchers like Gerling-Dunsmore to further explore their interests while learning new research skills. 

The DoD announced today the selection of nine distinguished faculty scientists and engineers for the 2022 Class of Vannevar Bush Faculty Fellows (VBFF). This highly competitive Fellowship is named in honor of Dr. Vannevar Bush, who directed the Office of Scientific Research and Development after World War II. In line with Dr. Bush’s vision, the Fellowship aims to advance transformative, university-based fundamental research.

“The Vannevar Bush Faculty Fellowship is the Department’s most prestigious research grant award,” said Dr. Jean-Luc Cambier, the VBFF Program Director. “It is oriented towards bold and ambitious ‘blue sky’ research that will lead to extraordinary outcomes that may revolutionize entire disciplines, create entirely new fields, or disrupt accepted theories and perspectives.” JILA and NIST Fellow Jun Ye has been distinguished as one of the 2022 Fellows. 

This year, JILA celebrates its 60th anniversary. Officially established on April 13, 1962, as a joint institution between the University of Colorado Boulder and the National Institute of Standards and Technology (NIST), JILA has become a world leader in physics research. Its rich history includes three Nobel laureates, groundbreaking work in laser development, atomic clocks, underlying dedication to precision measurement, and even competitive sports leagues. The process of creating this science goliath was not always straightforward and took the dedication and hard work of many individuals.

Two JILA graduate students were awarded this year's Richard Nelson Thomas Award for Graduate Students in Astrophyiscs. This award is given annually in honor of Dr. Richard Nelson Thomas, a founding member of JILA and an astrophysics researcher. Dr. Thomas was instrumental in establishing JILA's Visiting Fellows program, as well as growing the institution as a whole. Because of Dr. Thomas' legacy, his family and friends established an annual award given to an outstanding graduate student in astrophysics. 

University of Colorado President Todd Saliman visited JILA this past week and toured the laboratories at the invitation of JILA and NIST Fellow Eric Cornell.

Saliman was impressed by the research team and Fellows and applauded their work.

“You are all working to change the world,” President Saliman said.

Most, if not all, JILA alumni have found that their time at JILA has impacted their careers. Whether through working on cutting-edge research or networking with others, most JILA alumni have left the institution with essential skills needed for their future successes. This is the case for Dr. Rabin Paudel, who was a Senior Applications Engineer at Cymer/ASML, which is a Dutch multinational company that makes photolithography equipment used by semiconductor chipmakers. Since the writing of this article, Paudel has now started a new position at Intel Corporation.

For some physics and math undergraduates, JILA has become a place to learn cutting-edge research while belonging to a community. That's what undergraduate Connor Thomas experienced. Though Thomas is graduating with a bachelor's in biochemistry and transitioning to a graduate program at MIT, he's been grateful for his time at JILA. "JILA has been a pretty fantastic community for me," Thomas said. "In particular, my lab has been great. They were really constant through COVID. I am definitely going to miss all of that."

“It's hard to imagine my career without JILA,” explained Mike Martin, staff scientist at Los Alamos National Laboratory. Martin first arrived at CU in 2006, as a graduate student. “I began working with [JILA and NIST Fellow] Jun Ye in 2007,” he said. “My work was in frequency metrology for precision measurement and timekeeping.” During Martin's stint at JILA, he explained that he helped work on the early development of the frequency comb. As time continued, his work expanded to include studying the strontium lattice clock. “At the time there was only one strontium apparatus in Jun’s lab,” he said. “And around 10 people or so were all studying it.” This allowed him to collaborate with many other colleagues on the science behind the clock. 

World Quantum Day is a big deal for JILA. With around 75% of JILA Fellows researching quantum phenomena, it's no surprise that this institute is a world leader in this field. “Quantum research enables so many applications, varying from new generations of computers, secure communications, to ultraprecise clocks and sensors,” explained JILA Fellow Shuo Sun.  “In addition, quantum research will drive the advances of many fields such as material science, chemistry, nanoscience, etc., which will likely drive new technology breakthroughs that we cannot predict yet. Finally, the research in quantum allows us to probe the fundamental questions in physics, which is really fascinating to me.” Quantum physics has had a long history at JILA, becoming popular thanks to Einstein's work in the 1920s. Several JILA Fellows, including JILA and NIST Fellow Jun Ye, continue to build off of Einstein's original work. 

JILA W. M. Keck Lab has been selected to receive a CU Green Labs Program Award for the lab’s efforts for shared research resources. The annual CU Green Labs Awards Program started in 2015 to reward departments that work to make the campus' sustainability possible.  Awardees exemplify CU’s continuing efforts to become a sustainable institution. 

Founded in 1962, JILA (a partnership between CU Boulder and NIST) is a world leader in quantum sensing research, workforce training, and industry engagement. JILA scientists have helped develop technology that has been implemented in space, while others are looking into using lasers to help with diagnosing respiratory illnesses. Over time, though, age has taken a toll on JILA facilities. 

The CU Federal Relations team worked with senators Hickenlooper and Bennet to secure $950,000 in funding for JILA through the omnibus bill to give its labs a refresh.

According to JILA COO Beth Kroger, the funding will pay for much-needed research equipment in the JILA instrument and electronics shops, as well as equipment for CU Boulder’s JILA Keck Metrology and Clean Room Core Facility, which serves the campus and provides important research capabilities.

JILA Fellow Heather Lewandowski has been honored in the 2022  President’s Teaching Scholars Program (PTSP), which recognizes CU faculty who skillfully integrate teaching and research at an exceptional level. Lewandowski's laboratory focuses on both cold molecular physics and physics education research. Her physics education research program studies ways to increase students' proficiency in scientific practices such as using models and quantitative reasoning in experimental physics. 

JILA and NIST Fellow Ana Maria Rey is to be inducted into the Colombian Academy of Exact, Physical and Natural Sciences (Academia Colombiana de Ciencias Exactas, Fisicas y Naturales). Fellow Ana Maria Rey has been inducted into the Colombian National Academy of Sciences.  Rey, is a Colombian-American physicist at the University of Colorado, Boulder who "studies the scientific interface between atomic, molecular and optical physics, condensed matter physics and quantum information science."

This week has been a big week for Colorado's quantum community, as delegates from the Government of Finland visited the snowy state to celebrate the beginning of several quantum research and quantum technology partnerships between the Fins and both academia and industry-based groups in Colorado.
