Resurgent reentrant localization in a non-Hermitian quasiperiodic chain (opens in new tab)

Author(s): Haoyu Wang, Fuming Xu, Liantuan Xiao, Suotang Jia, Jun Chen, and Lei ZhangWe investigate localization transitions in a one-dimensional non-Hermitian quasiperiodic chain with period-2 mosaic modulation and nonreciprocal hopping. We show that tuning the degree of non-Hermiticity can induce a rich reentrant localization behavior: As the hopping asymmetry increases, reentrant…[Phys. Rev. B 113, 214204] Published Thu Jun 18, 2026
