标题： Quantum Chaos, Thermalization, and Non-locality

摘要： 在本文中，我们数值研究了由一个光谱表现出可积性的非局域哈密顿量引起的时光演化过程中是否发生量子热化。这个非局域且可积的哈密顿量是通过结合两种类型的可积哈密顿量构建的。从纠缠熵和互信息的时间依赖性来看，我们发现非局域性可以将系统演化到典型状态。另一方面，对数negativity的时间依赖性表明，非局域性可以破坏量子关联。这些发现表明，由非局域哈密顿量引起的量子热化不需要系统的量子混沌性。 显示英文摘要

摘要： In this paper, we numerically investigate whether quantum thermalization occurs during the time evolution induced by a non-local Hamiltonian whose spectra exhibit integrability. This non-local and integrable Hamiltonian is constructed by combining two types of integrable Hamiltonians. From the time dependence of entanglement entropy and mutual information, we find that non-locality can evolve the system into the typical state. On the other hand, the time dependence of logarithmic negativity shows that the non-locality can destroy the quantum correlation. These findings suggest that the quantum thermalization induced by the non-local Hamiltonian does not require the quantum chaoticity of the system.
