量子热输运中的选择律阻塞与校正

Selection-rule blockade and rectification in quantum heat transport

Teemu Ojanen

摘要:

我们介绍了一种新的热输运现象,单向选择规则封锁,并显示它如何产生前所未有的整流玻色子热流通过分子或介观量子系统。整流源于传导单元能级的量子化和储层耦合算子的选择规则。表现出选择规则封锁的最简单系统是适当耦合的三能级系统,为高性能热二极管提供了候选。我们提出了一个分析处理的运输问题,并讨论如何将这种现象推广到多层次的系统。

英文摘要:

We introduce a new thermal transport phenomenon, a unidirectional selection-rule blockade, and show how it produces unprecedented rectification of bosonic heat flow through molecular or mesoscopic quantum systems. Rectification arises from the quantization of energy levels of the conduction element and selection rules of reservoir coupling operators. The simplest system exhibiting the selection-rule blockade is an appropriately coupled three-level system, providing a candidate for a high-performance heat diode. We present an analytical treatment of the transport problem and discuss how the phenomenon generalizes to multilevel systems.
