摘要

放大（减缓）是指在存在约束条件的情况下，当初始热态热化到不同温度时，热力学量变化的增加（减少），迄今为止只研究了排列不变浴。在本文中，我们推广了放大和缓和，以适应开放量子系统的一般强对称性，并将这种现象与朗道尔擦除联系起来。我们用一个新的浴池诱导电池充电协议来举例说明我们的一般理论，该协议克服了kms保持转换的被动性。

Amplification, mitigation and energy storage via constrained thermalization

Amplification (mitigation) is the increase (decrease) in the change of thermodynamic quantities when an initial thermal state is thermalized to a different temperature in the presence of constraints, studied thus far only for permutationally invariant baths. In this manuscript, we generalize amplification and mitigation to accommodate generic strong symmetries of open quantum systems and connect the phenomenon to Landauer’s erasure. We exemplify our general theory with a new bath-induced battery charging protocol that overcomes the passivity of KMS-preserving transitions.

期刊介绍： Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
