Real-complex transition driven by quasiperiodicity: a new universality class beyond symmetric one
Tong Liu, Xu Xia
We study a one-dimensional lattice model subject to non-Hermitian quasiperiodic potentials. Firstly, we strictly demonstrate that there exists an interesting dual mapping relation…
Mobility edges in -symmetric cross-stitch flat band lattices
Tong Liu, Shujie Cheng
We study the cross-stitch flat band lattice with a -symmetric on-site potential and uncover mobility edges with exact solutions. Furthermore, we study the relationshi…
Fate of Majorana zero modes by a modified real-space-Pfaffian method and mobility edges in a one-dimensional quasiperiodic lattice
Shujie Cheng, Yufei Zhu, Gao Xianlong +1
We aim to study a one-dimensional -wave superconductor with quasiperiodic on-site potentials. A modified real-space-Pfaffian method is applied to calculate the topological invar…
Dual-mapping and quantum criticality in off-diagonal Aubry-André models
Tong Liu, Xu Xia
We study a class of off-diagonal quasiperiodic hopping models described by one-dimensional Su-Schrieffer-Heeger chain with quasiperiodic modulations. We unveil a general dual-mappi…
Fate of Majorana zero modes, critical states and non-conventional real-complex transition in non-Hermitian quasiperiodic lattices
Tong Liu, Shujie Cheng, Hao Guo +1
We study a one-dimensional -wave superconductor subject to non-Hermitian quasiperiodic potentials. Although the existence of the non-Hermiticity, the Majorana zero mode is still…
Generalized Aubry-André self-duality and Mobility edges in non-Hermitian quasi-periodic lattices
Tong Liu, Hao Guo, Yong Pu +1
We demonstrate the existence of generalized Aubry-André self-duality in a class of non-Hermitian quasi-periodic lattices with complex potentials. From the self-duality relations, t…
