JILA and NIST Fellow Jun Ye has been awarded the Niels Bohr Institute Medal of Honor for 2021. This award was established in 2010 to mark the 125th anniversary of Niels Bohr’s birth. The medal is awarded annually to a particularly outstanding researcher who is working in international cooperation and exchange of knowledge, two qualities exemplified by Bohr himself.
The second quantum revolution is underway, a period marked by significant advances in quantum technology, and huge discoveries within quantum science. From tech giants like Google and IBM, who build their own quantum computers, to quantum network startups like Aliro Quantum, companies are eager to profit from this revolution. However, doing so takes a new type of workforce, one trained in quantum physics and quantum technology. The skillset required for this occupation is unique, and few universities expose students to real-world quantum technology.
One of the major strengths of JILA are the frequent and ongoing collaborations between experimentalists and theorists, which have led to incredible discoveries in physics. One of these partnerships is between JILA Fellow John Bohn and JILA and NIST Fellow Jun Ye. Bohn's team of theorists has partnered with Ye's experimentalist laboratory for nearly twenty years, from the very beginning of Ye’s cold molecule research when he became a JILA Fellow. Recently in their collaborations, the researchers have been studying a three-dimensional molecular gas made of 40K87Rb molecules. In a paper published in Nature Physics, the combined team illustrated new quantum mechanical tricks in making this gas unreactive, thus enjoying a long life (for a gas), while at the same time letting the molecules in the gas interact and socialize (thermalize) with each other.
Breath analysis has been fast progressing in recent years and is continuing to gain more and more research interest. It is, however, experimentally challenging due to the extremely low concentrations of molecules present in each breath, limited number of detectable molecular species, and the long data-analysis time required. Now, a JILA-based collaboration between the labs of NIST Fellows Jun Ye and David Nesbitt has resulted in a more robust and precise breath-testing apparatus. In combining a special type of laser with a mirrored cavity, the team of researchers was able to precisely measure four molecules in human breath at unprecedented sensitivity levels, with the promise of measuring many more types of molecules.
Jun Ye, fellow at the National Institute of Standards and Technology (NIST) and professor adjoint of physics at ÃÛÌÒ´«Ã½Æƽâ°æÏÂÔØ, has been awarded the 2022 Breakthrough Prize in Fundamental Physics for his pioneering research on atomic clocks. Ye has been a physicist at JILA, a joint institute of NIST and ÃÛÌÒ´«Ã½Æƽâ°æÏÂÔØ, for more than 20 years.
In a new paper published in Physical Review Letters, JILA and NIST Fellows Eric Cornell, Jun Ye, and Konrad Lehnert developed a method for measuring a potential dark matter candidate, known as an axion-like particle. Axion-like particles are a potential class of dark matter particle which could explain some aspects of galactic structure. This work is also a result of collaboration with Victor Flambaum who is a leading theorist studying possible violations of fundamental symmetries.
The Department of Commerce is proud to join the Nation in recognizing the Asian American, Native Hawaiian, and Pacific Islander (AANHPI) Heritage Month, also known as Asian American Pacific Islander (AAPI) Heritage Month. Observed annually in May, AANHPI Heritage Month is a time to reflect upon and celebrate the remarkable role of the AANHPI community in our Nation’s history. It also is a time to recognize all the many contributions and achievements within the AAHNPI community that have had a positive impact on our Nation.
The 2021 Julius Springer Award for Applied Physics is awarded to Professor Jun Ye for pioneering research in fundamental quantum interactions of elemental matter and light, exploiting precision optical spectroscopy and laser-lattice atomic traps.
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.
