论文摘要
我们表征了多维二次超阻力系统的有限时间热力学过程。为系统协方差矩阵的任何演变提供了用于热，工作和耗散的分析表达式。协方差矩阵之间的Bures-Wasserstein指标自然出现为局部耗散量。讨论了如何应用这些几何工具来识别最佳协议的一般原则。为了关注相关的慢速驾驶极限，我们展示了如何使用这些结果来分析对系统的实验控制的案例。
We characterize finite-time thermodynamic processes of multidimensional quadratic overdamped systems. Analytic expressions are provided for heat, work, and dissipation for any evolution of the system covariance matrix. The Bures-Wasserstein metric between covariance matrices naturally emerges as the local quantifier of dissipation. General principles of how to apply these geometric tools to identify optimal protocols are discussed. Focusing on the relevant slow-driving limit, we show how these results can be used to analyze cases in which the experimental control over the system is partial.
