标题： Phase-dependent quantum correlation in cavity-atom system

摘要： 我们提出一种方案，通过相位控制来操控腔体两侧输出光的量子关联。 一个探测激光被设置为在干涉仪中分成两束，两臂之间有相对相位，分别沿腔轴相反方向驱动腔模。 这种相位在此被称为驱动场相位，对于在HBT（Hanbury Brown-Twiss）装置中建立量子关联非常重要。 三个控制激光垂直传播到腔轴，并以闭环相位驱动相应的原子跃迁。 这种闭环相位已在先前的工作中用于实现原子系统的量子关联甚至量子纠缠 [Phys. Rev. A 81 033836 (2010)]。 这里的方案有助于操控稳态和最大量子关联。 显示英文摘要

摘要： We propose a scheme to manipulate quantum correlation of output lights from two sides of a cavity by phase control. A probe laser is set to split into two beams in an interferometer with a relative phase in two arms which drive the cavity mode in opposite directions along cavity axis, individually. This phase, here named as driving-field phase, is important to build up quantum correlation in HBT (Hanbury Brown-Twiss) setup. Three control lasers propagate vertically to the cavity axis and drive the corresponding atomic transitions with a closed-loop phase. This type of closed-loop phase has been utilized to realize quantum correlation and even quantum entanglement of the atomic system in previous work [Phys. Rev. A 81 033836 (2010)]. The scheme here is useful to manipulate steady and maximum quantum correlation.
