论文摘要
热力学不确定性关系揭示了热系统波动与熵产生之间的有用联系。这项工作将这些想法扩展到\ textIt {零温度}量子介质物理学的不同场，在这些量子上是由于相干效应而引起的，熵产生被成本函数所取代。成本函数自然而然地是由于相干效应引起的波动而产生的，这是量子介质物理学中的关键资源。将成本函数确定为重要数量，这表明了将强大方法从非平衡统计物理学导入量子介质的潜力。
Thermodynamic uncertainty relations unveil useful connections between fluctuations in thermal systems and entropy production. This work extends these ideas to the disparate field of \textit{zero temperature} quantum mesoscopic physics where fluctuations are due to coherent effects and entropy production is replaced by a cost function. The cost function arises naturally as a bound on fluctuations, induced by coherent effects -- a critical resource in quantum mesoscopic physics. Identifying the cost function as an important quantity demonstrates the potential of importing powerful methods from non-equilibrium statistical physics to quantum mesoscopics.
