Phase-coherent multi-orbital bands of microcavity exciton-polaritons in a lattice

ORAL

Abstract

Microcavity exciton-polaritons are quantum bose particles arising from the strong light-matter coupling between cavity photons and quantum well excitons. They have been attractive entities to explore fundamental quantum nature phenomena in solid-state systems including Bose-Einstein condensation and superfluidity. Here we investigate phase-coherent multi-orbital bands of microcavity exciton-polaritons which are trapped in an artificial periodic lattice potential. Optical properties of the system are studied via photoluminescence imaging and spectroscopy at low temperatures.
