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…
