摘要翻译:
理解决定热传导宏观规律的潜在动力学机制是非平衡统计力学的一项长期任务。对热传导机理的更好理解可能会导致基于控制热流的潜在有趣的应用。事实上,最近提出了不同的热整流器模型,在这些模型中,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,但底层机制具有非常普遍的性质,因此适合改进,并可能最终导致真正的应用。本文简要讨论了经典系统和量子系统中的热输运问题及其与动力学混乱度的关系。然后我们研究了热整流现象,并简要讨论了导致热流整流的不同类型的微观机制。

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.
