经典和量子系统中的热流与热整流

Heat Flow in Classical and Quantum Systems and Thermal Rectification

Giulio Casati, Carlos Mejia-Monasterio

摘要:

对决定热传导宏观规律的基本动力学机制的理解是非平衡统计力学的一项长期任务。更好地理解热传导的机制可能会导致基于控制热流的可能性的潜在有趣的应用。事实上,最近已经提出了不同型号的热整流器,其中热量可以优先沿一个方向流动。虽然这些模型离原型实现还很远,但基本机制具有非常普遍的性质,因此适合改进,并可能最终导致实际应用。我们简要地讨论了经典和量子系统中的热输运问题及其与动力学混沌性的关系。然后,我们研究热整流现象,并简要讨论了不同类型的微观机制,导致整流的热流。

英文摘要:

The understanding of the underlying dynamical mechanisms which determine the macroscopic laws of heat conduction is a long standing task of non-equilibrium statistical mechanics. A better understanding of the mechanism of heat conduction may lead to potentially interesting applications based on the possibility to control the heat flow. Indeed, different models of thermal rectifiers has been recently proposed in which heat can flow preferentially in one direction. Although these models are far away from a prototype realization, the underlying mechanisms are of very general nature and, as such, are suitable of improvement and may eventually lead to real applications. We briefly discuss the problem of heat transport in classical and quantum systems and its relation to the chaoticity of the dynamics. We then study the phenomenon of thermal rectification and briefly discuss the different types of microscopic mechanisms that lead to the rectification of heat flow.
