Microscopic theory of polariton-polariton interactions
Esben R. Christensen, Arturo Camacho-Guardian, Ovidiu Cotlet +4
We develop a comprehensive theoretical model for the interaction strength between a pair of exciton-polaritons in microcavity devices. Ab initio numerical calculations for dipolar…
