摘要:

本综述介绍了非均匀XX自旋链研究的最新进展,重点介绍了完美态传输、开放系统中的非平衡稳态动力学以及基态中的纠缠和关联的结果。我们讨论了实现完美态传输的耦合条件,研究了当链与热浴耦合时热流如何缩放,探讨了三对角矩阵在近似纠缠哈密顿量中的作用,并研究了体相和边界纠缠负性以及关联衰减。这些发现强调了非均匀自旋链的一些独特物理行为及其在量子信息和热输运中的潜在应用。

英文摘要:

This review presents recent developments in the study of inhomogeneous XX spin chains, highlighting results on perfect state transfer, out-of-equilibrium stationary dynamics in open systems, and entanglement and correlations in ground states. We discuss the conditions on couplings that enable perfect state transfer, examine how heat currents scale when the chains are coupled to thermal baths, explore the role of tridiagonal matrices in approximating the entanglement Hamiltonian and investigate bulk and boundary entanglement negativity and correlation decay. These findings underscore some of the distinctive physical behavior of inhomogeneous spin chains and their potential applications in quantum information and thermal transport.
