Анализ экситонной люминесценции в мезорезонаторах на основе GaN

We considered the interaction of an exciton mode with photonic eigenmodes in a GaN structure with several μm in size. A technique for obtaining spectra from such structures is demonstrated. The most optimal shape and dimensions of the resonator were selected for effective interaction of light and matter. The theoretical spectrum for the selected resonator is obtained and analyzed.

CONTINUOUS-VARIABLE ENTANGLEMENT OF THE CAVITY AND EXCITON MODE

We consider a semiconductor quantum well in the excitation system. Applying the pertinent Hamiltonian, we investigate the second-order intensity correlation function and the entanglement properties between the cavity and exciton mode. It is found that nonclassical (antibunching) effect and sudden death effect occur in our system.

Theory of a phonon–exciton resonance in a molecular crystal

The theory of a coupled phonon–roton (rotational exciton) mode in a molecular crystal is developed using the propagator technique. The dispersion relation and the phonon density of states are calculated. The results are applied to the case of solid HD. The line-shape function for the one phonon branch, phonon–roton coupling, and the roton band frequencies are calculated for this case. Near the phonon–roton resonance, the one phonon branch shows strong influence of the interaction with the roton band.
