控制孤立系的量子临界动力学

Controlling quantum critical dynamics of isolated systems

A. del Campo, K. Sengupta

摘要:

控制孤立量子系统通过临界点的非绝热动力学在从量子模拟到有限时间热力学的各种领域都很有意义。我们简要地回顾了不同的方法设计协议,最大限度地减少激发(缺陷)的生产在一个封闭的量子临界系统驱动的平衡。我们绘制出具体的驱动方案的作用,这一过程中,指出他们的实验相关性,并讨论其实施的背景下,超冷原子和自旋系统。

英文摘要:

Controlling the non adiabatic dynamics of isolated quantum systems driven through a critical point is of interest in a variety of fields ranging from quantum simulation to finite-time thermodynamics. We briefly review the different methods for designing protocols which minimize excitation (defect) production in a closed quantum critical system driven out of equilibrium. We chart out the role of specific driving schemes for this procedure, point out their experimental relevance, and discuss their implementation in the context of ultracold atom and spin systems.
