Coupling a quantum many-body system to an external environment dramatically changes its dynamics and offers novel possibilities not found in closed systems. Of special interest are the properties of the steady state of such open quantum many-body systems, as well as the relaxation dynamics toward the steady state. However, new computational tools are required to simulate open quantum many-body systems, as methods developed for closed systems cannot be readily applied. Several approaches to simulating open many-body systems are reviewed, and advances made in recent years toward the simulation of large system sizes are pointed out.

开放量子多体系统的仿真方法

将量子多体系统耦合到外部环境会极大地改变其动力学,并提供封闭系统中找不到的新颖可能性。特别令人感兴趣的是这种开放量子多体系统的稳态特性,以及向稳态的弛豫动力学。然而,由于不能轻易应用为封闭系统开发的方法,因此需要新的计算工具来模拟开放量子多体系统。综述了几种模拟开放式多体系统的方法,并指出了近年来在模拟大型系统中所取得的进展。
