Observation of bosonic condensation in a hybrid monolayer MoSe-GaAs microcavity.

Bosonic condensation belongs to the most intriguing phenomena in physics, and was mostly reserved for experiments with ultra-cold quantum gases. More recently, it became accessible in exciton-based solid-state systems at elevated temperatures. Here, we demonstrate bosonic condensation driven by excitons hosted in an atomically thin layer of MoSe, strongly coupled to light in a solid-state resonator.
