论文摘要
我提出了一种计算基于马尔可夫嵌入的结构化储层的系统中有限频率量子噪声的方法。该技术包括将原始系统的非马克维亚动力学映射到扩展超级系统的马尔可夫动力学上。该方法的适用性在单个电子水平上证明，该电子水平耦合到具有能量依赖性状态密度的储层。该模型可以映射到等效的双层系统，该系统的动力学由Markovian Master方程式控制。事实证明，所提出的方法提供了一种描述真正量子效应的方法，例如吸收和发射噪声的不对称性，以及处理非马克维亚效应和在同等基础上的非马克维亚效应和系统内相互作用。
I present an approach to calculate the finite-frequency quantum noise in systems strongly coupled to structured reservoirs based on the Markovian embedding. This technique consists of mapping of the non-Markovian dynamics of the original system onto the Markovian dynamics of the extended supersystem. The applicability of this method is demonstrated on a single electronic level coupled to a reservoir with an energy-dependent density of states. This model can be mapped onto an equivalent double-level system whose dynamics is governed by an exact Markovian master equation. It is demonstrated that the presented approach provides a way to describe genuinely quantum effects, such as the asymmetry of the absorption and the emission noise, as well as to deal with non-Markovian effects and intra-system interactions on equal footing.
