In a prestigious acknowledgment of scientific impact, JILA and NIST Fellow Jun Ye has been awarded the 2023 "Highly Cited" researcher designation from Clarivate. This notable recognition is bestowed upon researchers whose work ranks in the top 1% of citations for their field, highlighting their significant influence in the scientific community.
As reported in a new Science Advances paper, the JILA team and collaborators from universities in Sweden, Greece, and Germany probed the spin dynamics within a special material known as a Heusler compound: a mixture of metals that behaves like a single magnetic material. For this study, the researchers utilized a compound of cobalt, manganese, and gallium, which behaved as a conductor for electrons whose spins were aligned upwards and as an insulator for electrons whose spins were aligned downwards.
New research from JILA Fellow and University of Colorado Boulder physics professor Cindy Regal and her team, Dr. Ravid Shaniv and graduate student Chris Reetz has found that in specific scenarios, such as advanced studies looking at the interactions between light and mechanical objects, where the temperature might differ in various resonator parts, which lead to unexpected behaviors. Their observations, published in Physical Review Research, can potentially revolutionize the design of micro-mechanical resonators for quantum technology and precision sensing.
U.S. President Joe Biden has awarded 232聽Senior Executive Service (SES), Senior-Level (SL), and Scientific and Professional (ST) members across 31 government agencies with the prestigious Presidential Rank Award. Of these individuals, JILA and NIST Fellow Ana Maria Rey has been recognized within the Department of Commerce for her work in precision measurement and quantum physics.
In quantum information science, many particles can act as 鈥渂its,鈥 from individual atoms to photons. At JILA, researchers utilize these bits as 鈥渜ubits,鈥 storing and processing quantum 1s or 0s through a unique system.
While many JILA Fellows focus on qubits found in nature, such as atoms and ions, JILA Associate Fellow and University of Colorado Boulder Assistant Professor of Physics Shuo Sun is taking a different approach by using 鈥渁rtificial atoms,鈥 or semiconducting nanocrystals with unique electronic properties. By exploiting the atomic dynamics inside fabricated diamond crystals, physicists like Sun can produce a new type of qubit, known as a 鈥渟olid-state qubit,鈥 or an artificial atom.
JILA Fellow Murray Holland and his research team proposed an algorithm that uses the Quantum Fisher Information Matrix (QFIM), a set of mathematical values that can determine the usefulness of entangled states in a complicated system.
Their results, published in Physical Review Letters as an Editor鈥檚 Suggestion, could offer significant benefits in developing the next generation of quantum sensors by acting as a type of 鈥渟hortcut鈥 to find the best measurements without needing a complicated model.
Recently graduated Ph.D. researchers Bin Wang and Nathan Brooks, working with JILA Fellows Margaret Murnane and Henry Kapteyn, developed a novel method that uses short-wavelength light with a special vortex or donut shape to scan these repeating surfaces, resulting in more varied diffraction patterns. This allowed the researchers to capture high-fidelity image reconstructions using this new approach, which they recently published in Optica.
To honor students' abilities for clear and effective communication in quantum physics, Optica offers a yearly "best paper" award at its International Conference on Advanced Solid State Lasers. This year, JILA graduate student Daniel Carlson was among the list of winners, with his presentation "Carbon K-Edge Soft X-Rays Driven by a 3 碌m,1 kHz OPCPA Laser System" winning over the judges.
On October 20th, Colorado Senator Michael Bennet visited JILA, a joint institute between the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder. During his visit, Bennet engaged with several of the institute's scientists and students, discussing their groundbreaking research and its implications. JILA Fellows Konrad Lehnert, Cindy Regal, Jun Ye, and Ana Maria Rey all spoke about their research during Bennett鈥檚 walking tour of JILA. Bennet visited Ye鈥檚 laboratory, discussing with several of his students the importance of atomic clocks and their impacts on technology such as GPS.
Bennet's engagement with JILA reinforces the significance of Colorado as a hub for scientific innovation and quantum research, and it sheds light on the potential collaborations that could emerge between political leadership and the scientific community.
Every year, the Colorado Photonics Industry Association (CPIA) holds a university meeting where students from several of Colorado's prominent universities present their work as a poster to an industry audience, followed by networking with potential employers. For students, it's an excellent opportunity to practice public speaking, share their current research projects, and find potential industry jobs. Each year, three students are awarded a cash prize for how well they communicate their research and the design of their poster.
This year, JILA graduate students Qizhong Liang, from JILA and NIST Fellow Jun Ye's research group, and Drew Morrill, from JILA Fellows Margaret Murnane's and Henry Kapteyn's research group, have been awarded prizes for their poster presentations.
