and anti- phase transitions in a trimerized Su--Schrieffer--Heeger chain with nonreciprocal Rashba spin-orbit coupling
Milad Jangjan, Linhu Li, Longwen Zhou +1
We theoretically investigate a one-dimensional trimerized Su--Schrieffer--Heeger chain with three sublattices per unit cell subjected to a nonreciprocal Rashba spin-orbit coupling.…
Non-Hermitian topological Euler insulators
Longwen Zhou
Topological Euler insulators emerge in multiband systems with real Bloch Hamiltonians and wavefunctions. Their fragile topologies are characterized by the Euler class of degenerate…
Topological metal-insulator transitions in one-dimensional non-Hermitian quasicrystals: beyond PT-symmetry
Guangjie Zhang, Bing Shao, Longwen Zhou +2
One-dimensional non-Hermitian quasicrystals with parity and time-reversal (PT) symmetry can simultaneously exhibit localization-delocalization transition, topological phase transit…
Lateral Shift as a Control Knob for Localization Transitions in a Quasiperiodic Ladder
Bing Shao, Guangjie Zhang, Longwen Zhou +2
This work reports rich localization-delocalization transitions in a quasiperiodic ladder, of which the two legs are subject to the same quasiperiodic onsite potential but can be sh…
Topology and edge modes surviving criticality in non-Hermitian Floquet systems
Longwen Zhou
The discovery of critical points that can host quantized nonlocal order parameters and degenerate edge modes relocate the study of symmetry-protected topological phases (SPTs) to g…
