双阱系统中的量子动力学和输运

Quantum dynamics and transport in a double well system

Itamar Sela, Doron Cohen

摘要:

研究非平凡几何效应的最简单的一维模型是由两个臂连接而成的环形装置。我们探讨的可能性,这样的系统作为一个两级系统(TLS)建模。特别感兴趣的是量子搅动的分析,其中不明显的是,拓扑结构在TLS建模的框架内得到了适当的反映。在技术方面,我们提供了一个实用的“邻近水平”近似的量子器件的分析,即使TLS建模不适用,它仍然有效。

英文摘要:

The simplest one-dimensional model for the studying of non-trivial geometrical effects is a ring shaped device which is formed by joining two arms. We explore the possibility to model such a system as a two level system (TLS). Of particular interest is the analysis of quantum stirring, where it is not evident that the topology is properly reflected within the framework of the TLS modeling. On the technical side we provide a practical "neighboring level" approximation for the analysis of such quantum devices, which remains valid even if the TLS modeling does not apply.
