JILA Fellow and NIST Physicist and ÂÌñ»»ÆÞ Physics Professor Adam Kaufman and his team, along with collaborators at NIST (the National Institute of Standards and Technology), have demonstrated a novel method of boson sampling using ultracold atoms (specifically, bosonic atoms) in a two-dimensional optical lattice of intersecting laser beams.
In a new paper published in Science, JILA and NIST Fellows Ana Maria Rey and James Thompson, JILA Fellow Murray Holland, and their teams proposed a way to overcome atomic recoil by demonstrating a new type of atomic interaction called momentum-exchange interaction, where atoms exchanged their momentums by exchanging corresponding photons.
The Heising-Simons Foundation's Science program has announced a generous grant of $3 million over three years, aimed at bolstering theoretical and experimental research efforts to bridge the realms of Atomic, Molecular, and Optical (AMO) physics with quantum gravity theories. Among the recipients, a notable grant was awarded to a multi-investigator collaboration spearheaded by the ÂÌñ»»ÆÞ (ÂÌñ»»ÆÞ) and JILA, a joint institute of ÂÌñ»»ÆÞ and the National Institute of Standards and Technology (NIST).
Ana Maria Rey and her team discovered a method for how to not only create dark states in a cavity, but more importantly, make these states spin squeezed. Their findings could open remarkable opportunities for generating entangled clocks, which could push the frontier of quantum metrology in a fascinating way.
In a new study published in Science today, JILA and NIST (National Institute of Standards and Technology) Fellow and ÂÌñ»»ÆÞ physics professor Jun Ye and his research team have taken a significant step in understanding the intricate and collective light-atom interactions within atomic clocks, the most precise clocks in the universe.
As a thermodynamic phase of matter, superconductors typically exist in an equilibrium state. But recently, researchers at JILA became interested in kicking these materials into excited states and exploring the ensuing dynamics. As reported in a new Nature paper, the theory and experiment teams of JILA and NIST Fellows Ana Maria Rey and James K. Thompson, in collaboration with Prof. Robert Lewis-Swan at the University of Oklahoma, simulated superconductivity under such excited conditions using an atom-cavity system.
In a new Optica paper, Ye’s team, working with JILA electronic staff member Ivan Ryger and John "Jan" Hall, describe implementing a new approach for the PDH method, reducing RAM to never-before-seen minimal levels while simultaneously making the system more robust and simpler.
Nick Jenkins, a graduate student at JILA, an institute jointly operated by the ÂÌñ»»ÆÞ and the National Institute of Standards and Technology (NIST), has been awarded the esteemed Nick Cobb Memorial Scholarship. Mentored by JILA Fellows and ÂÌñ»»ÆÞ professors Margaret Murnane and Henry Kapteyn, Jenkins' research focuses on pioneering tabletop extreme ultraviolet (EUV) microscopy techniques using high-harmonic generation light sources. This innovative work has positioned him as a standout recipient of this significant award.
In an exciting turn for physics research, four major foundations have announced a collaborative funding effort for 11 pioneering "tabletop" experiments. The Gordon and Betty Moore Foundation, the Simons Foundation, the Alfred P. Sloan Foundation, and the John Templeton Foundation have come together, committing a total of $30 million. This unique initiative focuses on supporting experiments that, despite their relatively modest scale, are set to delve into areas often reserved for large-scale facilities.
Among the funded projects, each of which will receive up to five years of financial support, is a particularly notable experiment led by JILA and NIST Fellow Jun Ye and his research team. Known for his remarkable work in physics, Ye's project stands out for its ambition and innovative approach. The experiment involves the development of ultra-precise atomic clocks, which are expected to significantly advance our understanding of both quantum mechanics and general relativity.
Anjun Chu, a JILA graduate student, has been awarded the esteemed Boeing Quantum Creators Prize for 2023. This prestigious award, established by Boeing in 2021, celebrates early-career researchers who have significantly contributed to the advancement of quantum information science and engineering.
Chu, a member of the theory group led by JILA and NIST Fellow Ana Maria Rey, has distinguished himself through his groundbreaking research in quantum many-body dynamics. His work, focusing on spin systems and their multilevel extensions, has been vital in exploring quantum simulation and metrology in cutting-edge areas like optical lattice clocks and cavity QED systems.
