论文摘要
当工程微观机器工程机器时,提高效率通常会因随机波动的影响而以降低的可靠性而产生。在这里,我们开发了一种通用方法,用于在经典或量子状态下在接近平衡的热机中对效率和工作波动进行多目标优化。我们的方法利用了热力学几何形状的技术,从而将最佳解决方案与通过其热力学长度参数的协议进行匹配。我们表征了连续可变高斯机器的最佳方案,该方案在微观系统的热力学研究中构成了至关重要的类别。
When engineering microscopic machines, increasing efficiency can often come at a price of reduced reliability due to the impact of stochastic fluctuations. Here we develop a general method for performing multi-objective optimisation of efficiency and work fluctuations in thermal machines operating close to equilibrium in either the classical or quantum regime. Our method utilises techniques from thermodynamic geometry, whereby we match optimal solutions to protocols parameterised by their thermodynamic length. We characterise the optimal protocols for continuous-variable Gaussian machines, which form a crucial class in the study of thermodynamics for microscopic systems.
