摘要

研究了单量子比特诺维科夫量子热机与经典诺维科夫热机的异同。我们发现它们具有相似的功率效率曲线，但生态功能效率曲线却截然不同。我们的分析表明，在量子引擎中，功率和生态功能的最大值以及它们产生的效率取决于热耦合和量子比特的能量，这些量子比特的能量诱导了使引擎工作的热流。为了更好地理解经典诺维科夫热机与量子诺维科夫热机的异同，我们对量子热机的高温极限进行了分析。

Unified trade-off optimization of one-qubit Novikov heat engines

We study the similarities and differences between one-qubit Novikov quantum heat engines and classic Novikov heat engines. We find that they have similar power-efficiency curves but very different ecological function-efficiency curves. Our analysis shows that in quantum engines the maximum values of the power and ecological function, and the efficiencies at which they are produced depend on the thermal couplings and the energy of the qubit inducing the heat flux that makes the engine to work. We analyze the high-temperature limit of the quantum engines to understand better the similarities and differences between the classic and quantum Novikov heat engines.
