标题： Heat diode and engine based on quantum Hall edge states

摘要： 我们研究三端量子霍尔导体中的电荷和能量传输。 样品边缘沿手性传播的特殊性质对热偏置的响应有重要影响。 基于电荷和热量流的分离，可以通过调节门控调制收缩处的散射来操控热电转换和热整流。 磁场中的手性运动使得左移和右移载流子表现出不同的行为，通过重新定向热量流产生热整流。 我们提出的系统既可以作为高效的热能-动能转换器，也可以作为热二极管。 显示英文摘要

摘要： We investigate charge and energy transport in a three-terminal quantum Hall conductor. The peculiar properties of chiral propagation along the edges of the sample have important consequences on the response to thermal biases. Based on the separation of charge and heat flows, thermoelectric conversion and heat rectification can be manipulated by tuning the scattering at gate-modulated constrictions. Chiral motion in a magnetic field allows for a different behaviour of left- and right-moving carriers giving rise to thermal rectification by redirecting the heat flows. We propose our system both as an efficient heat-to-work converter and as a heat diode.
