Abstract

Recent advances in applying thermodynamic ideas to quantum systems have raised the novel prospect of using non-thermal, non-classical sources of energy, of purely quantum origin, like quantum statistics, to extract mechanical work in macroscopic quantum systems like Bose–Einstein condensates. On the other hand, thermodynamic ideas have also been applied to small systems like single molecules and quantum dots. In this paper, we study the quantum thermodynamics of small systems of anyons, with specific emphasis on the quantum Otto engine which uses, as its working medium, just one or two anyons. Formulae are derived for the efficiency of the Otto engine as a function of the statistics parameter.

小型系统的量子热力学奥托引擎
将热力学思想应用于量子系统的最新进展,为利用非热、非经典、纯量子源能量(如量子统计量)在玻色-爱因斯坦凝聚物等宏观量子系统中提取机械功带来了新的前景。另一方面,热力学思想也被应用于单个分子和量子点等小系统。在本文中,我们研究了由任子组成的小系统的量子热力学,并特别强调了量子奥托引擎,该引擎仅使用一个或两个任子作为工作介质。我们推导出了奥托引擎效率与统计参数函数的关系式。
