台球系统中的热电输运

Thermoelectric transport in billiard systems

Giulio Casati, Carlos Mejia-Monasterio

摘要:

我们讨论了热电(TE)输运在台球系统的相互作用的粒子,耦合到随机粒子水库。最近在文献[1]中,得到了多原子分子非相互作用气体TE输运的精确解析表达式,并描述了热电效率提高的一种新的微观机理。本文在简要回顾文献[1]的推导过程后,着重讨论了粒子间相互作用对TE效率的影响。我们表明,相互作用降低了最大热力学效率。然而,[1]中描述的效率向卡诺上限增加的机制仍然不受影响。

英文摘要:

We discuss the thermoelectric (TE) transport in billiard systems of interacting particles, coupled to stochastic particle reservoirs. Recently in [1], analytical exact expressions for the TE transport of noninteracting gases of polyatomic molecules were obtained, and a novel microscopic mechanism for the increase of thermoelectric efficiency described. After briefly reviewing the derivation of [1], in this paper we focus on the effects that the particle-particle interaction has on the TE efficiency. We show that interaction reduces the maximal thermodynamic efficiency. However, the mechanism for the efficiency's increase towards its Carnot upper limit, described in [1], remains unaffected.
