摘要:

反绝热驱动(CD)利用辅助控制场来调整量子系统的非平衡动力学,使得有限时间热力学中耗散功的抑制和无摩擦的最佳热机工程成为可能。我们表明,虽然辅助控制所做的平均工作消失,CD导致扩大的工作分布。我们推导出一个基本不等式,涉及非平衡工作波动的操作时间和量化的热力学成本CD在临界和非临界系统。

英文摘要:

Counterdiabatic driving (CD) exploits auxiliary control fields to tailor the nonequilibrium dynamics of a quantum system, making possible the suppression of dissipated work in finite-time thermodynamics and the engineering of optimal thermal machines with no friction. We show that while the mean work done by the auxiliary controls vanishes, CD leads to a broadening of the work distribution. We derive a fundamental inequality that relates nonequilibrium work fluctuations to the operation time and quantifies the thermodynamic cost of CD in both critical and noncritical systems.
