论文摘要
基于由颗粒组成的浴缸的量子类似物的引入少量连贯性的量子，从而启动了一系列积极的研究线，以利用不同的量子资源来增强超出标准可逆极限的热机器，重点是对含有量子量的非热疗法。在我们的工作中，我们研究了连贯性对碰撞模型热力学任务的影响，该模型由在连续的时限内相互作用的系统组成，并在不同温度下使用了一系列两个浴缸的相干杂质。我们的结果表明，将连贯性作为机器运行中的资源的优势，并允许：（i）表现出非常规的行为，例如杂交冰箱的出现，能够同时制冷和生成工作，并且（II）起发动机或冰箱的功能，具有比型号更大的冰箱。此外，我们发现有效的上限与在存在连贯的储层存在下作为发动机运行的热机的效率有效。
The introduction of the quantum analogue of a Carnot engine based on a bath comprising of particles with a small amount of coherence initiated an active line of research on the harnessing of different quantum resources for the enhancement of thermal machines beyond the standard reversible limit, with an emphasis on non-thermal baths containing quantum coherence. In our work, we investigate the impact of coherence on the thermodynamic tasks of a collision model which is composed of a system interacting, in the continuous time limit, with a series of coherent ancillas of two baths at different temperatures. Our results show the advantages of utilising coherence as a resource in the operation of the machine, and allows it: (i) to exhibit unconventional behaviour such as the appearance of a hybrid refrigerator, capable of simultaneous refrigeration and generation of work, and (ii) to function as an engine or a refrigerator with efficiencies larger than the Carnot bound. Moreover, we find an effective upper bound to the efficiency of the thermal machine operating as an engine in the presence of a coherent reservoir.
