讲座人介绍：
Igor Chestnov received his PhD degree in laser physics in the Moscow General Physics Institute in 2014. Later he worked on a postdoc position in Vladimir State University in Russia until 2018 when he became a research associate professor in the Westlake University in Hangzhou. Now he is a senior researcher in ITMO university in Russia. His research interests lie in semiconductor physics, photonics, quantum optics, laser physics and nonlinear dynamics.
报告主题：
This lecture will review the recent progress in investigating a spontaneous build-up of macroscopic coherence in non-resonantly pumped semiconductor microcavities. Because of the strong interaction between excitons and cavity mode, the hybrid particles called polaritons appear. Inheriting high mobility and strong interactions from their constituents, these particles demonstrate superfluid behavior accompanied by spontaneous nucleation of vortices. I will describe experimental approaches for creation and manipulation of such peculiar structures including spatial confinement techniques. In addition, I will present a theoretical framework capable of explaining a number of recent experimental findings.
