摘要

腔体光学机械学探索光与机械系统之间通过辐射压力产生的相互作用。这一跨学科领域融合了量子力学和量子光学的原理,为生成和控制量子态提供了强大的工具。在这项研究中,我们从理论上研究了光机械学背景下的四级 N 原子系统。振荡镜具有随位置变化的质量,并表现出奇异性。我们使用海森堡-朗格文方程分析了动力学,计算了稳态解,并通过分析和数值方法研究了光学响应。这项研究的重点是位置相关有效质量域内的光学响应。我们的研究结果表明,代表透射的输出场会随着与位置有关的有效质量的非线性参数 α $$ \alpha $$ 的变化和移动而变化。这些变化不仅影响传输,还会改变输出场的色散和相位。

Optical Response of a Position-Dependent Optomechanical System With N-Type Four-Level Atoms

Cavity optomechanics explores the interaction between light and mechanical systems through radiation pressure. This interdisciplinary field merges principles from quantum mechanics and quantum optics provides powerful tools for generating and controlling quantum states. In this research, we theoretically investigated a four-level N-atomic system within the context of optomechanics. The oscillating mirror possesses a mass that varies with position and exhibits a singularity. We analyzed the dynamics using Heisenberg–Langevin equations and calculated steady-state solutions, studied optical response through both analytical and numerical methods. The main focus of this study was optical response within the domain of position-dependent effective mass. Our findings revealed that the output field representing transmission exhibits variations and shift with α $$ \alpha $$ , the nonlinear parameter of the position dependent effective mass. These variations not only impact transmission but also alter the dispersion and phase of the output field.

期刊介绍: Since its first formulation quantum chemistry has provided the conceptual and terminological framework necessary to understand atoms, molecules and the condensed matter. Over the past decades synergistic advances in the methodological developments, software and hardware have transformed quantum chemistry in a truly interdisciplinary science that has expanded beyond its traditional core of molecular sciences to fields as diverse as chemistry and catalysis, biophysics, nanotechnology and material science.
