Dual-species atomic absorption image reconstruction using deep neural networks
Kyuhwan Lee, Yong-il Shin
Optical imaging plays an instrumental role in understanding the behavior of trapped neutral atoms. In this work, we describe a deep learning-based online image completion protocol…
Flattening a trapped atomic gas using a programmable optical potential in a feedback loop
Sol Kim, Kyuhwan Lee, Jongmin Kim +1
We present a method for producing a flat, large-area Fermi gas of Li with a uniform area density. The method uses a programmable optical potential within a feedback loop to fla…
Observation of universal Kibble-Zurek scaling in an atomic Fermi superfluid
Kyuhwan Lee, Sol Kim, Taehoon Kim +1
Half a century ago, T. Kibble proposed a scenario for topological defect formation from symmetry breaking during the expansion of the early Universe. W. Zurek later crystallized th…
Spin-driven stationary turbulence in spinor Bose-Einstein condensates
Deokhwa Hong, Junghoon Lee, Jongmin Kim +4
We report the observation of stationary turbulence in antiferromagnetic spin-1 Bose-Einstein condensates driven by a radio-frequency magnetic field. The magnetic driving injects en…
Critical Energy Dissipation in a Binary Superfluid Gas by a Moving Magnetic Obstacle
Joon Hyun Kim, Deokhwa Hong, Kyuhwan Lee +1
We study the critical energy dissipation in an atomic superfluid gas with two symmetric spin components by an oscillating magnetic obstacle. Above a certain critical oscillation fr…
