论文摘要
热机执行有用的任务 - 例如生产工作，冷却或加热 - 通过交换能量，并可能与储存库一样额外的保守量（例如颗粒）。在这里，我们考虑了同时执行多项有用任务的热机器，称为这些“混合热机”。我们概述了热力学定律施加的限制，并根据效率量化了它们的性能。为了说明它们的全部潜力，考虑了具有多个保守数量的储层（由广义吉布斯集团描述）。引入了混合热机的最小模型，其中包含三个储层和两个保守量，例如能量和粒子数。该模型可以根据量子点容易在热电设置中实现，并且考虑到现实参数，可以访问混合机制。
Thermal machines perform useful tasks--such as producing work, cooling, or heating--by exchanging energy, and possibly additional conserved quantities such as particles, with reservoirs. Here we consider thermal machines that perform more than one useful task simultaneously, terming these "hybrid thermal machines". We outline their restrictions imposed by the laws of thermodynamics and we quantify their performance in terms of efficiencies. To illustrate their full potential, reservoirs that feature multiple conserved quantities, described by generalized Gibbs ensembles, are considered. A minimal model for a hybrid thermal machine is introduced, featuring three reservoirs and two conserved quantities, e.g., energy and particle number. This model can be readily implemented in a thermoelectric setup based on quantum dots, and hybrid regimes are accessible considering realistic parameters.
