热力学极限下的热整流

Thermal rectification in the thermodynamic limit

Shunjiang You, Daxing Xiong, Jiao Wang

摘要:

我们发现,越来越强的热整流效应发生在热力学极限在一个一维的,梯度转子晶格与最近邻的相互作用。其基本机制是从正常的过渡到异常的热传导行为在相应的均匀晶格中观察到的温度降低。与此相反,除了通过调用远程相互作用,这一发现提供了一个独特的情况下,使热整流效果鲁棒。

英文摘要:

We show that an increasingly strong thermal rectification effect occurs in the thermodynamic limit in a one-dimensional, graded rotor lattice with nearest-neighboring interactions only. The underlying mechanism is related to the transition from normal to abnormal heat conduction behavior observed in the corresponding homogeneous lattices as the temperature decreases. In contrast and in addition to that by invoking long-range interactions, this finding provides a distinct scenario to make the thermal rectification effect robust.
