Dissipative structures of quantized vortices in a coherently pumped polariton superfluid

TL;DR

This paper investigates the formation of quantized vortex patterns in a coherently pumped polariton superfluid, revealing spontaneous symmetry breaking and steady-state structures unique to nonequilibrium dissipative systems.

Contribution

It demonstrates the spontaneous formation of vortex patterns and symmetry breaking in a pumped polariton superfluid, highlighting phenomena specific to nonequilibrium quantum fluids.

Findings

Vortex patterns emerge as pump parameters vary.

Translational symmetry is spontaneously broken.

Steady states exhibit unique dissipative structures.

Abstract

Steady states reached in a coherently pumped exciton-polariton superfluid are investigated. As the pump parameter is changed, the translational symmetry of the uniform system is spontaneously broken, and various steady patterns of quantized vortices are formed. This is peculiar to nonequilibrium dissipative systems with continuous pumping.
