Abstract: Exciton polaritons (EP) are partial-light partial-matter quasiparticles in semiconductors demonstrating striking quantum phenomena such as Bose-Einstein condensation and single-photon nonlinearity. In these phenomena, the governing process is the EP relaxation into the ground states upon… read more here.

Abstract: We study the exciton condensation phenomena in low-buckled two-dimensional semiconductors. Starting from the tight-binding effective Hamiltonian and considering the spin–orbit coupling as well as Rashba interaction induced by external electric field, we solve the gap… read more here.

Abstract: We present a scheme of interaction-induced topological band structures based on the spin anisotropy of exciton-polaritons in semiconductor microcavities. We predict theoretically that this scheme allows the engineering of topological gaps, without requiring a magnetic… read more here.
