Exciton-Polaritons


What is a polariton?


An exciton-polariton is a hybrid particle which consists of a photon (a particle of light) trapped in a reflective cavity which is strongly coupled to an exciton (a pseudo particle consisting of an electron and a hole).


As a Bosonic particle, exciton-polaritons possess unique intrinsic features. For example, they maintain remnants of their excitonic nature which leads to interesting interaction dynamics, for example Bose-Einstein condensation, a polaritonic Feshbach resonance, self and cross branch interactions, and excitation induced dephasing.
