Lieb-Robinson界与格点系统局部观测量时间演化的模拟

Lieb-Robinson bounds and the simulation of time evolution of local observables in lattice systems

Martin Kliesch, Christian Gogolin, Jens Eisert

摘要:

这是一个介绍性的文本审查利布罗宾逊界限开放和封闭的量子多体系统。我们介绍了海森堡图片依赖于时间的本地Liouvillians和状态的Lieb-Robinson界,产生了最大的传播速度的相关性在许多机构系统的本地相互作用的自旋和费米子。最后,我们讨论了一些重要的后果有关的时间演化和基态和定态的性质的模拟。

英文摘要:

This is an introductory text reviewing Lieb-Robinson bounds for open and closed quantum many-body systems. We introduce the Heisenberg picture for time-dependent local Liouvillians and state a Lieb-Robinson bound that gives rise to a maximum speed of propagation of correlations in many body systems of locally interacting spins and fermions. Finally, we discuss a number of important consequences concerning the simulation of time evolution and properties of ground states and stationary states.
