2 Apr 2020 | | Abstract: | The Kibble-Zurek mechanism constitutes one of the most fascinating and
universal phenomena in the physics of critical systems. It describes the
formation of domains and the spontaneous nucleation of topological defects when
a system is driven across a phase transition exhibiting spontaneous symmetry
breaking. While a characteristic dependence of the defect density on the speed
at which the transition is crossed was observed in a vast range of equilibrium
condensed matter systems, its extension to intrinsically driven-dissipative
systems is a matter of ongoing research. In this work we numerically confirm
the Kibble-Zurek mechanism in a paradigmatic family of driven-dissipative
quantum systems, namely exciton-polaritons in microcavities. Our findings show
how the concepts of universality and critical dynamics extend to
driven-dissipative systems that do not conserve energy or particle number nor
satisfy a detailed balance condition. | | Source: | arXiv, 2004.0918 | | Services: | Forum | Review | PDF | Favorites | |
