Time resolved heat exchange in driven quantum systems

Maria Florencia Ludovico, Jong Soo Lim, Michael Moskalets, Liliana Arrachea, David Sanchez

摘要:

我们研究了由周期性外加电源强迫的共振能级和耦合到费米子连续体组成的系统中的含时热输运。这个简单的模型包含了理解量子电容器中时间分辨能量交换的基本成分,量子电容器表现为单粒子发射器。我们分析的行为的动态热流驱动频率内的非绝热制度,表明它不遵守焦耳耗散定律。

英文摘要:

We study time-dependent heat transport in systems composed of a resonant level periodically forced with an external power source and coupled to a fermionic continuum. This simple model contains the basic ingredients to understand time resolved energy exchange in quantum capacitors that behave as single particle emitters. We analyse the behaviour of the dynamic heat current for driving frequencies within the non-adiabatic regime, showing that it does not obey a Joule dissipation law.
