Stochastic circular persistent currents of exciton polaritons

Abstract We monitor the orbital degree of freedom of exciton-polariton condensates confined within an Plates optical trap and unveil the stochastic switching of persistent annular polariton currents under pulse-periodic excitation.Within an elliptical trap, the low-lying in energy polariton current states manifest as a two-petaled density distribution with a swirling phase.In the stochastic regime, the density distribution, averaged over multiple excitation pulses, becomes homogenized in the azimuthal direction.Meanwhile, the 3 Piece Twin Sleigh Bed weighted phase, extracted from interference experiments, exhibits two compensatory jumps when varied around the center of the trap.

Introducing a supplemental control optical pulse to break the reciprocity of the system enables the transition from a stochastic to a deterministic regime, allowing for controlled polariton circulation direction.
