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…
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…
One dimensional quasiperiodic mosaic lattice with exact mobility edges
Yucheng Wang, Xu Xia, Long Zhang +5
The mobility edges (MEs) in energy which separate extended and localized states are a central concept in understanding the localization physics. In one-dimensional (1D) quasiperiod…
Realization and detection of non-ergodic critical phases in optical Raman lattice
Yucheng Wang, Long Zhang, Sen Niu +2
The critical phases, being delocalized but non-ergodic, are fundamental phases which are different from both the many-body localization and ergodic extended quantum phases, and hav…
