| Abstract: | The quantum properties of the exciton in a leaky cavity with quasi modes were investigated. It is shown that there exists energy exchange between the exciton and cavity field when the cavity is initially in the vacuum state, and the exciton is initially in a superposition of the vacuum state and number state. The exciton and the cavity field may exhibit sub Poissonian distribution. The correlation between the exciton and the cavity is classical, which implies that there has no violation of the Cauchy Schwartz inequality. |
