Exciton-polaritons are quasiparticles formed by strongly coupling a photon confined in a cavity to an electron-hole pair in a semiconductor. These quasiparticles are bosonic and have an astonishingly low effect mass, allowing them to undergo condensation at temperatures much higher than those associated with gases of dilute atoms. In 2014, a non-equiliibrium BEC was observed at room temperature in an exicton-polariton system for a period of about 12 picoseconds. This talk will discuss the basic physics of Bose-Einstein condensation and exciton-polariton condesates, and how these systems allow us to investigate BEC physics without cooling down to nanokelvin temperatures.
