本论文研究了以下与光相关的四个关键概念： 研究了在介电介质附近产生磁卡西米尔-波尔德力的位置相关兰姆位移。已经研究了靠近介电介质的自发发射导致指数衰减偏差的记忆效应。发射器-探测器系统受诺特定理的启发，用于研究介电体附近的光子动量传递。使用量子光学框架在迈克尔逊-莫雷干涉仪中研究了经典光和量子光的时间相干干涉效应。本论文的主要目的是讨论光的经典描述和量子描述之间的关系。经典描述通常提供更简单的方法，使人们更容易理解系统的基础知识。然而，某些效应只能通过量子力学描述来获得。薛定谔方程已被用来寻找满足麦克斯韦方程的量子化电磁场的时间演化。量化过程不能使用标准量化方案来执行。因此，二进格林函数形式被用于耗散系统，以利用涨落耗散定理来量化场。在描述光子探测器时应用了光电探测的格劳伯理论。分析方法已在可达到的范围内使用，其中传统和专门开发的数值方法做出了巨大贡献。由于完全量化系统的复杂性迅速增加，因此通过使用经典电磁理论添加动态边界条件来简化所研究的系统。
This thesis is an investigation of the following four key concepts related to light: The position dependent Lamb-shift giving rise to a magnetic Casimir-Polder force close to a dielectric medium has been studied. Memory effects causing a deviation from exponential decay has been studied for spontaneous emission close to a dielectric medium. An emitter-detector system is motivated by Noether's theorem to study the photon momentum transfer near a dielectric body. Temporal coherence interference effects of classical and quantum light is studied in the Michelson-Morley interferometer using a quantum-optics framework.The major object of interest for this thesis is the discussion of the relationship between the classical and the quantum description of light. A classical description often give a simpler approach making it easier to understand the fundamentals of the system. However, some effects are only obtained using a quantum mechanically description.The Schrodinger equation has been used to find the time-evolution of a quantized electromagnetic field satisfying the Maxwell equations. The quantization procedure cannot be carried out using the standard quantization scheme. A dyadic Green's function formalism has therefore been used for the dissipative system to quantize the field using the fluctuation-dissipation theorem. Glauber theory of photodetection has been applied when describing the photon detectors. Analytical methods have been used to the achievable extent, with a substantial contribution from conventional and specially developed numerical methods. Since the fully quantized system rapidly increases in complexity, the investigated system is simplified by adding dynamic boundary conditions using classical electromagnetic theory.
