摘要

我们考虑一个微腔中有一个激子的量子阱，该微腔最初包含光子，并与一个单模压缩真空储层耦合。利用量子朗之万方程的解研究了低激发状态下激子模的强度、二阶相关函数、强度谱和正交压缩。虽然初始腔光子增加了激子模式的强度，但它们对正交压缩有不利影响。我们还证明了激子模式表现出正交压缩，压缩量随着输入压缩光的增加而增加。

Quantum Statistical and Squeezing Properties in a Semiconductor Cavity QED

We consider a quantum well with one exciton in a microcavity that initially contains photons and is coupled to a one-mode squeezed vacuum reservoir. The solution of the quantum Langevin equation is used to investigate the intensity, second-order correlation function, intensity spectrum, and quadrature squeezing of the exciton mode in the low-excitation regime. Although the initial cavity photons increase the intensity of the exciton mode, they have an adverse effect on the quadrature squeezing. We also demonstrate that the exciton mode exhibits quadrature squeezing, with the amount of squeezing increased by the input squeezed light.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
