Exact non-Hermitian mobility edges in one-dimensional quasicrystal lattice with exponentially decaying hopping and its dual lattice
Yanxia Liu, Yongjian Wang, Zuohuan Zheng +1
We analytically determine the non-Hermitian mobility edges of a one-dimensional quasiperiodic lattice model with exponential decaying hopping and complex potentials as well as its…
Exact mobility edges, -symmetry breaking and skin effect in one-dimensional non-Hermitian quasicrystals
Yanxia Liu, Yucheng Wang, Xiong-Jun Liu +2
We propose a general analytic method to study the localization transition in one-dimensional quasicrystals with parity-time () symmetry, described by complex quasiper…
Localization transition, spectrum structure and winding numbers for one-dimensional non-Hermitian quasicrystals
Yanxia Liu, Qi Zhou, Shu Chen
By analyzing the Lyapunov exponent (LE), we develop a rigorous, fundamental scheme for the study of general non-Hermitian quasicrystals with both complex phase factor and non-recip…
Non-Hermitian mobility edges in one-dimensional quasicrystals with parity-time symmetry
Yanxia Liu, Xiang-Ping Jiang, Junpeng Cao +1
We investigate localization-delocalization transition in one-dimensional non-Hermitian quasiperiodic lattices with exponential short-range hopping, which possess parity-time ($\mat…
Diagnosis of bulk phase diagram of non-reciprocal topological lattices by impurity modes
Yanxia Liu, Shu Chen
We study the single impurity problem in the non-Hermitian lattice described by the non-reciprocal Su-Schrieffer-Heeger model and obtain the phase diagram of localized bound states…
