Characterization of Spin-Driven Stationary Turbulence in Spinor Bose-Einstein Condensates
POSTER
Abstract
This poster presents our observation of stationary turbulence in antiferromagnetic spin-1 Bose-Einstein condensates under radio-frequency magnetic field driving. The magnetic driving injects energy into the system by spin rotation and the energy is dissipated via dynamic instability, resulting in the development of an irregular spin texture in the condensate. With continuous driving, the spinor condensate evolves into a nonequilibrium steady state with characteristic spin turbulence. To enrich our understanding, we explored various system parameters determining features of the turbulence. One of our findings is that as the driving strength approaches the system's intrinsic energy scale, the spin composition of the stationary turbulence becomes isotropic. We will also discuss the roles of driving frequency, noise and quadratic Zeeman energy on the emergence of spin turbulence.
