Probing the Dynamics of Spontaneous Quantum Vortices in Polariton Superfluids. Physical Review Letters, 106, 115301-. | Series/Report no.: | Physical Review Letters | Abstract: | 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. We formulate a theoretical model that successfully reproduces the experimental observations. | URI: | https://hdl.handle.net/10356/85897 http://hdl.handle.net/10220/43899 |
