Energy spectra and cascade in the spin turbulence of a driven spinor Bose-Einstein condensate
Junghoon Lee, Jongmin Kim, Donggyu Lee +1
We investigate the spin-interaction energy spectrum of spin turbulence in a driven spinor Bose-Einstein condensate. Continuous spin driving of a spin-1 condensate produces a nonequ…
Efficient ensemble randomization by tuning chaos in a nonlinear spin-1 system
Jongmin Kim, Minsung Jeong, Jongyoon Han +1
We present an efficient scheme to randomize a spin-state ensemble in a nonlinear spin-1 system by tuning chaos with an external periodic drive. Without modulation, the system exhib…
Enhancement of damping in a turbulent atomic Bose-Einstein condensate
Junghoon Lee, Jongmin Kim, Jongheum Jung +1
Turbulence enhances momentum transport in classical fluids, effectively increasing their viscosity. We investigate an analogous effect in a superfluid by measuring the damping of c…
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…
Chaos-assisted Turbulence in Spinor Bose-Einstein Condensates
Jongmin Kim, Jongheum Jung, Junghoon Lee +2
We present a turbulence-sustaining mechanism in a spinor Bose-Einstein condensate, which is based on the chaotic nature of internal spin dynamics. Magnetic driving induces a comple…
Random spin textures in turbulent spinor Bose-Einstein condensates
Jong Heum Jung, Junghoon Lee, Jongmin Kim +1
We numerically investigate the stationary turbulent states of spin-1 Bose-Einstein condensates under continuous spin driving. We analyze the entanglement entropy and magnetization…
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…
