Precision Measurement
In a new study published in Scientific Reports, JILA Fellow and ñ physics professor Andreas Becker and his team theorized a new method to produce extreme ultraviolet (EUV) and x-ray light with elliptical polarization, a special shape in which the direction of light waves’ oscillation is changing. This method could provide experimentalists with a simple technique to generate such light, which is beneficial for physicists to further understand the interactions between electrons in materials on the quantum level, paving the way for designing better electronic devices such as circuit boards, solar panels, and more.
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.
New research from JILA Fellow and ñ 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.
Every year, the Czech Science Foundation (GCAR) funds several JUNIOR STAR projects focused on new research areas and building powerful collaborative teams. These projects are awarded to early-career scientists coming to the Czech Republic from other countries or with significant international experience. Each project is awarded CZK 25 million over the following five years.
This year, JILA postdoctoral researcher Vít Svoboda is one of the 17 awardees in the 2023 JUNIOR STAR cohort.
U.S. President Joe Biden has awarded 232 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 “bits,” from individual atoms to photons. At JILA, researchers utilize these bits as “qubits,” 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 ñ Assistant Professor of Physics Shuo Sun is taking a different approach by using “artificial atoms,” 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 “solid-state qubit,” 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’s Suggestion, could offer significant benefits in developing the next generation of quantum sensors by acting as a type of “shortcut” 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 µm,1 kHz OPCPA Laser System" winning over the judges.
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.
