考虑了双模腔内含有N个三能级V型原子的系综与两个量子化场之间的相互作用。在非绝热消除原子变量的条件下，分析了两个初始为相干态的输入场从腔内输出后的量子关联性质。结果表明在恰当的条件下，在中心频率处可以获得量子纠缠，但随合作参数的增加，中心频率处的纠缠变小甚至消失。与此同时，在高频区间则产生了一对边频量子纠缠。这是由于合作参数增加引起的真空拉比分裂导致了高频处获得量子关联。此外，通过调节量子化场的强度以及原子和场的反对称失谐，还可获得两对边频量子纠缠。这对边频量子关联的研究具有十分重要的价值。

The interaction of two quantized fields with an atomic ensemble including N three-level V-type atoms inside a two-mode cavity is investigated. With nonadiabatic elimination, the quantum correlation properties of two output cavity fields are analyzed when the two initial input fields are in coherent states. The results show that the quantum entanglement can be generated at the zero frequency under appropriate conditions. As the cooperation parameter increases, the zero-frequency entanglement decreases, and even vanishes. However, a pair of sideband entanglement happen in the high-frequency regime, which are induced by vacuum Rabi splitting. In addition, by modifying the intensity of the quantized fields and the antisymmetric detunings, two pairs of sideband entanglement can also be obtained. These results will benefit the research of the sideband quantum correlations.
