Anomalous localization and duality in non-Hermitian quasiperiodic models
Wenzhi Wang, Tianyu Li, Wei Yi
Boundary conditions can have dramatic impact in non-Hermitian systems, as exemplified by the non-Hermitian skin effect. Focusing on one-dimensional non-Hermitian quasiperioidic lat…

Family of self-dual quasicrystals with critical Phases
Wenzhi Wang, Wei Yi, Tianyu Li
We propose a general framework for constructing self-dual one-dimensional quasiperiodic lattice models with arbitrary-range hoppings and multifractal behaviors. Our framework gener…

Dynamic transition of the density-matrix topology under parity-time symmetry
Wenzhi Wang, Wei Yi
Density-matrix topology, defined through the geometric property of the relevant modular Hamiltonian, can undergo transitions in the corresponding open-system dynamics. While symmet…
