研究目的

Exploring the conditions of occupation and emission of exciton states in quantum dots coupled to a microcavity in the presence of an external and tilted magnetic field.

研究成果

The inclusion of an external and tilted magnetic field in the Tavis-Cummings model allows for the exploration of the occupation and emission conditions of exciton states in quantum dots coupled to a microcavity. The magnetic field serves as a control parameter to select which exciton state and which quantum dot will be mostly coupled to the cavity. A notable finding is the trace of emission from dark excitons, which are optically inactive, due to the interaction between bright and dark exciton states mediated by the magnetic field.

研究不足

The study does not consider the decay of dark excitons by additional carriers or spin-flip processes, focusing instead on the effect of the resonant properties of two quantum dots mediated by the magnetic field. The simulations are conducted under very low temperatures.
