Probing the dynamics of spontaneous quantum vortices in polariton superfluids
The experimental investigation of spontaneously created vortices is of utmost importance for
the understanding of quantum phase transitions towards a superfluid phase, especially for
two-dimensional systems that are expected to be governed by the Berezinski-Kosterlitz-
Thouless physics. By means of time-resolved near-field interferometry we track the path of
such vortices, created at random locations in an exciton-polariton condensate under pulsed
nonresonant excitation, to their final pinning positions imposed by the stationary disorder …
