阻尼相干态与波包量子干涉

The Damping Coherent State and Quantum Interference

本文参照相干态定义和合阻尼及无规力的朗之万方程定义了阻尼相干态，并应用于计算波包间的量子干涉。在一般情况下，对于一个合阻尼的系统，波包间产生的于涉条纹将很快消失而很难观察到，但当真空场被压缩时，就清楚地显示出波包间的量子干涉效应。

In this paper the damping coherent state is defined taking into account the interference of damping on the coherent state,and the quantum interference between wave packets is calculated.In general,for a disspative system the quantum interference fringes produced by the wave packets disappear in the last, but we can still observe the quantum interference effect if the vaccum is squeezed,ie, the isotrope of vaccum is destroyed.
