英文摘要: We investigate the quantum decoherence of a mesoscopically superposed states of excitons in a quantum well placed within a leaky cavity. Based on the factorization theory of quantum dissipation, our investigation shows that the coherence of the superposed states of the excitons will decrease in an oscillating form when the cavity field is of the quasimode form. Regarding the effects of the thermal cavity fields on the quantum decoherence of the superposition states of the exciton: we observe that the higher the temperature of the environment, the shorter the decoherence characteristic time.
