Isolated extended states and anomalous critical behavior in the generalized SSH model
Jia-Ming Zhang
We investigate the localization properties of a generalized SSH model. Numerical and analytical results indicate the emergence of extended states protected by unbounded hopping in…

Emergent extended states in an unbounded quasiperiodic lattice
Jia-Ming Zhang, Shan-Zhong Li, Shi-Liang Zhu +1
Previous studies have established that quasiperiodic lattice models with unbounded potentials can exhibit localized and multifractal states, yet preclude the existence of extended…

Emergent strength-dependent scale-free mobility edge in a non-reciprocal long-range Aubry-André-Harper model
Gui-Juan Liu, Jia-Ming Zhang, Shan-Zhong Li +1
We investigate the properties of mobility edge in an Aubry-André-Harper model with non-reciprocal long-range hopping. The results reveal that there can be a new type of mobility e…
