EMISSION SPECTRUM OF A QUANTUM DOT IN A MICROCAVITY IN THE BIEXCITONIC REGIME: A PERSPECTIVE FROM GREEN’S FUNCTIONS THEORY

Abstract

We found a closed expression for the correlation functions for the solid state system: a quantum dot modeled as a four-level atom coupled with a light-mode of two polarization degrees of freedom, through a calculation based on Greens functions theory, as an alternative from quantum regression theorem. From these functions we found the emission spectrum and then we recovered certain strong coupling and photoluminiscence phenomena like the anticrossing of the emission modes of the system and the so called two-photon transitions.
