Hidden-symmetry-protected topological phases on a one-dimensional lattice
Linhu Li, Shu Chen
We demonstrate the existence of topologically nontrivial phase in a one-dimensional fermionic lattice system subjected to synthetic gauge fields, which is beyond the standard Altla…
Topological incommensurate magnetization plateaus in quasi-periodic quantum spin chains
Hai-Ping Hu, Chen Cheng, Hong-Gang Luo +1
Uncovering topologically nontrivial states in nature is an intriguing and important issue in recent years. While most studies are based on the topological band insulators, the topo…
Kaleidoscope of symmetry protected topological phases in one-dimensional periodically modulated lattices
Huaiming Guo, Shu Chen
We identify the existence of various symmetry-protected topological states in one-dimensional superlattices with periodically modulated hopping amplitudes or on-site potentials, wh…
PT-Symmetry in Non-Hermitian Su-Schrieffer-Heeger model with complex boundary potentials
Baogang Zhu, Rong Lu, Shu Chen
We study the parity- and time-reversal PT symmetric non-Hermitian Su-Schrieffer-Heeger (SSH) model with two conjugated imaginary potentials at two end sites. The SSH model…
Dynamical Anderson transition in one-dimensional periodically kicked incommensurate lattices
Pinquan Qin, Chuanhao Yin, Shu Chen
We study the dynamical localization transition in a one-dimensional periodically kicked incommensurate lattice, which is created by perturbing a primary optical lattice periodicall…
