论文摘要
讨论了热光子和挤压光子之间的争吵相互作用。 “经典噪声”由热光子表示，“量子噪声”由挤压光子表示，这些光子在相干场的背景下相互对立（由相干光子表示）。用于此目的的光子计数分布（PCD）与挤压相干热状态相对应。据观察，通过分别将PCD定位和定位的PCD添加热光子和挤压光子具有平衡效应。已经研究了原子场相互作用的各个方面，例如原子倒置，杰伊斯 - 夏明林模型中的纠缠动态。由于在连贯状态中添加热和挤压光子，因此特别注意原子反转和纠缠动态的研究。热光子和挤压光子的相互作用对原子场相互作用的PCD，原子反转和纠缠动态具有巨大影响。
The tussling interplay between the thermal photons and the squeezed photons is discussed. The `classical noise' is represented by the thermal photons and the `quantum noise' is represented by the squeezed photons, which are pitted against each other in the background of a coherent field (represented by the coherent photons). The photon counting distribution (PCD) corresponding to the squeezed coherent thermal states are employed for this purpose. It is observed that the addition of thermal photons and squeezed photons have counterbalancing effects, by delocalizing and localizing the PCD, respectively. Various aspects of the atom-field interaction, like the atomic inversion, entanglement dynamics in the Jaynes-Cummings model have been investigated. Particular attention is given to the study of atomic inversion and entanglement dynamics due to the addition of thermal and squeezed photons to the coherent state. The interplay of thermal photons and squeezed photons have drastic effects on the PCD, atomic inversion and entanglement dynamics of the atom-field interaction.
