    JILA postdoctoral researcher Simon Scheidegger has received the prestigious METAS 2024 Award from the Swiss Physical Society (SPS). Scheidegger, who is part of JILA and NIST Fellow Jun Ye's laboratory group, was awarded for his pioneering research on precise measurements of hydrogen energy levels during his PhD at ETH Zurich.
  • Pulse sequences for generating two-axis twisting rotate the spins of KRb molecules, transforming the spin exchange interactions.
    The interactions between quantum spins underlie some of the universe鈥檚 most interesting phenomena, such as superconductors and magnets. However, physicists have difficulty engineering controllable systems in the lab that replicate these interactions.

    Now, in a recently published Nature paper, JILA and NIST Fellow and University of Colorado Boulder Physics Professor Jun Ye and his team, along with collaborators in Mikhail Lukin鈥檚 group at Harvard University, used periodic microwave pulses in a process known as Floquet engineering, to tune interactions between ultracold potassium-rubidium molecules in a system appropriate for studying fundamental magnetic systems. Moreover, the researchers observed two-axis twisting dynamics within their system, which can generate entangled states for enhanced quantum sensing in the future.
