Topological order versus many-body localization in periodically modulated spin chains

29 Nov 2019 Orito Takahiro Kuno Yoshihito Ichinose Ikuo

In this paper, we study periodically modulated $s=1/2$ spin chain in a linear gradient potential (LP) that is generated by an external magnetic field. In the absence of the LP, the system has topological states that exhibit a magnetization plateau for a uniform external magnetic field... (read more)
