Hidden Unbounded Potential and Re-Entrant Multifractalization in a Generalized Su-Schrieffer-Heeger Model
Yun-Yan Chen, Jia-Ming Zhang, Zhi Li
We study the multifractal criticality in a generalized Su-Schrieffer-Heeger model. The results show that the system supports not only critical phases but also re-entrance multifrac…

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…
