论文摘要
连接到三个热浴的三级系统被操纵为一个微观热装置，集成了阀门，冰箱，放大器和量子状态中的温度计，通过调谐系统的内部耦合强度和外部浴缸的温度。我们使用Redfield Master方程在部分世俗近似下讨论了内部耦合以及稳态量子相干性的作用。在没有系统内部耦合的情况下，可以建立用于低温终端的高敏温度计。我们对这项多功能热装置的研究为与量子相干性相关的基本量子热力学提供了更深入的见解。
A three-level system attached to three thermal baths is manipulated to be a microscopic thermal device integrating a valve, a refrigerator, an amplifier, and a thermometer in the quantum regime, via tuning the inner coupling strength of the system and the temperatures of the external baths. We discuss the role of the inner coupling as well as the steady-state quantum coherence in these thermal functions using the Redfield master equation under a partial secular approximation. A high-sensitive thermometer for the low-temperature terminal can be established without the assistance from the inner coupling of the system. Our study of this multifunctional thermal device provides a deeper insight to the underlying quantum thermodynamics associated with the quantum coherence.
