General mapping of one-dimensional non-Hermitian mosaic models to non-mosaic counterparts: Mobility edges and Lyapunov exponents
Sheng-Lian Jiang, Yanxia Liu, Li-Jun Lang
We establish a general mapping from one-dimensional non-Hermitian mosaic models to their non-mosaic counterparts. This mapping can give rise to mobility edges and even Lyapunov exp…
A general approach to the exact localized transition points of 1D mosaic disorder models
Yanxia Liu
In this paper, we present a general correspondence between the mosaic and non-mosaic models, which can be used to obtain the exact solution for the mosaic ones. This relation holds…
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…
