Abstract

Recently, Kumar Gerry et al. [Phys. Rev. A 90, 033427 (2014)] studied the coherence control in a six-level atom through solving the Schrödinger equation in the field-interaction representation. In this manuscript, we investigate the interaction between a six-level atomic system (SLAS) and a single-mode field initially prepared in a squeezed coherent state. We extend the Jeans-Cummings model to describe the interaction between the atom and the squeezed field (SF) and the system dynamics. We examine the time evolution of the atomic coherence, non-local correlation, statistical properties within the bipartite system in the presence and absence intensity-dependent coupling (I-DC) for different squeezing regimes of the field.

原子场系统:压缩和强度相关耦合对量子相干性和非经典性质的影响

最近，Kumar Gerry等人。通过求解场相互作用表示中的Schrödinger方程，研究了六能级原子的相干性控制[j] .光子学报(自然科学版)，2014,31(4):444 - 444。在本文中，我们研究了六能级原子系统(SLAS)与最初在压缩相干态中制备的单模场之间的相互作用。我们扩展了jean - cummings模型来描述原子与压缩场(SF)之间的相互作用和系统动力学。我们研究了在存在和不存在强度相关耦合(I-DC)的情况下，在不同的场压缩制度下，二部系统内原子相干性，非局部相关性，统计性质的时间演化。

期刊介绍： Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry. Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research. The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics. The journal covers both fundamental and applied topics, including but not limited to: Classical and quantum optics Light/matter interaction Optical communication Micro- and nanooptics Nonlinear optical phenomena Optical materials Optical metrology Optical spectroscopy Colour research Nano and metamaterials Modern photonics technology Optical engineering, design and instrumentation Optical applications in bio-physics and medicine Interdisciplinary fields using photonics, such as in energy, climate change and cultural heritage The journal aims to provide readers with recent and important achievements in optics/photonics and, as its name suggests, it strives for the shortest possible publication time.
