摘要

本文介绍了一种利用考希-施瓦茨不等式推导子系统熵产生率下限的方法。它扩展到为两个子系统的效率建立全面的上界和下界。这些界限适用于多种马尔可夫随机过程，从而提高了描述子系统间能量转换效率范围的准确性。我们使用双量子点系统模型进行了经验验证，证实了我们的不等式在完善效率边界方面的有效性。

Efficiency bounds for bipartite information-thermodynamic systems

In this paper, we introduce an approach to derive a lower bound for the entropy production rate of a subsystem by utilizing the Cauchy-Schwarz inequality. It extends to establishing comprehensive upper and lower bounds for the efficiency of two subsystems. These bounds are applicable to a wide range of Markovian stochastic processes, which enhances the accuracy in depicting the range of energy conversion efficiency between subsystems. Empirical validation is conducted using a two-quantum-dot system model, which serves to confirm the effectiveness of our inequality in refining the boundaries of efficiency.
