Dissipative structures of quantized vortices in a coherently pumped polariton superfluid
Dissipative structures of quantized vortices in a coherently pumped polariton superfluid
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.
