论文摘要
以有限功率运行的可爱的热机器的性能构成了非平衡经典和量子热力学，工程等的主要挑战之一。我们介绍了调整交互时间不对称的想法，以优化发动机性能。我们考虑了最简单的热机之一，它是由量子点依次与两个不同的热和颗粒储层相互作用的量子点组成的。在随机热力学的框架中分析了不同的优化方案。结果表明，不对称的相互作用时间在增强功率输出方面起着基本作用，最大化可以提供大于25 \％对称情况的增加。作为一个额外的优势，对于广泛的储层温度，最大功率的效率略大于可厌食的Curzon-Ahlborn效率。
The performance of endoreversible thermal machines operating at finite power constitutes one of the main challenges of nonequilibrium classical and quantum thermodynamics, engineering and others. We introduce the idea of adjusting the interaction time asymmetry in order to optimize the engine performance. We consider one of the simplest thermal machines, composed of a quantum dot interacting sequentially with two different reservoirs of heat and particles. Distinct optimization protocols are analyzed in the framework of stochastic thermodynamics. Results reveal that asymmetric interaction times play a fundamental role in enhancing the power output and that maximizations can provide an increase larger than 25\% the symmetric case. As an extra advantage, efficiencies at maximum power are slightly greater than the endoreversible Curzon-Ahlborn efficiency for a broad range of reservoir temperatures.
