Pauli-Fierz模型中能量输运的大偏差母函数

Large deviation generating function for energy transport in the Pauli-Fierz model

Wojciech De Roeck

摘要:

考虑了不同温度下与准自由热库耦合的有限量子系统。在小耦合和油藏关联函数指数衰减的假设下,证明了油藏能量输运的大偏差母函数在有界集上是解析的。我们的方法不同于最近在类自旋玻色子模型研究中采用的谱形变技术。作为推论,我们导出了熵产生的Gallavotti-Cohen涨落关系和能量输运的中心极限定理。

英文摘要:

We consider a finite quantum system coupled to quasifree thermal reservoirs at different temperatures. Under the assumptions of small coupling and exponential decay of the reservoir correlation function, the large deviation generating function of energy transport into the reservoirs is shown to be analytic on a bounded set. Our method is different from the spectral deformation technique which was employed recently in the study of spin-boson-like models. As a corollary, we derive the Gallavotti-Cohen fluctuation relation for the entropy production and a central limit theorem for energy transport.
