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…

Duality between two generalized Aubry-Andre models with exact mobility edges
Yucheng Wang, Xu Xia, Yongjian Wang +2
A mobility edge (ME) in energy separating extended from localized states is a central concept in understanding various fundamental phenomena like the metal-insulator transition in…
