Non-Hermitian pseudo mobility edge in a coupled chain system
Sen Mu, Longwen Zhou, Linhu Li +1
In this work, we explore interesting consequences arising from the coupling between a clean non-Hermitian chain with skin localization and a delocalized chain of the same length un…
Dimerization induced mobility edges and multiple reentrant localization transitions in non-Hermitian quasicrystals
Wenqian Han, Longwen Zhou
Non-Hermitian effects could create rich dynamical and topological phase structures. In this work, we show that the collaboration between lattice dimerization and non-Hermiticity co…
Topological delocalization transitions and mobility edges in the nonreciprocal Maryland model
Longwen Zhou, Yongjian Gu
Non-Hermitian effects could trigger spectrum, localization and topological phase transitions in quasiperiodic lattices. We propose a non-Hermitian extension of the Maryland model,…
Floquet engineering of topological localization transitions and mobility edges in one-dimensional non-Hermitian quasicrystals
Longwen Zhou
Time-periodic driving fields could endow a system with peculiar topological and transport features. In this work, we find dynamically controlled localization transitions and mobili…
Non-Hermitian quasicrystal in dimerized lattices
Longwen Zhou, Wenqian Han
Non-Hermitian quasicrystals possess PT and metal-insulator transitions induced by gain and loss or nonreciprocal effects. In this work, we uncover the nature of localization transi…
Non-Hermitian topological phases and dynamical quantum phase transitions: A generic connection
Longwen Zhou, Qianqian Du
The dynamical and topological properties of non-Hermitian systems have attracted great attention in recent years. In this work, we establish an intrinsic connection between two cla…
