Single vortex-antivortex pair in an exciton polariton condensate

ORAL

Abstract

We report the observation of a single vortex-antivortex pair in a two-dimensional exciton polariton condensate. The pairs are evidenced in the time-integrated phase maps acquired using Michelson interferometry. The striped pattern of the sample disorder potential prevents rotation of the pairs, but allows their translational movement.
