Berezinskii-Kosterlitz-Thouless localization-localization transitions in disordered two-dimensional quantized quadrupole insulators
C. Wang, Wenxue He, Hechen Ren +1
Anderson localization transitions are usually referred to as quantum phase transitions from delocalized states to localized states in disordered systems. Here we report an unconven…
Anderson localization transitions in disordered non-Hermitian systems with exceptional points
C. Wang, X. R. Wang
The critical exponents of continuous phase transitions of a Hermitian system depend on and only on its dimensionality and symmetries. This is the celebrated notion of the universal…
Chiral Hinge Transport in Disordered Non-Hermitian Second-Order Topological Insulators
C. Wang, X. R. Wang
The generalized bulk-boundary correspondence predicts the existence of the chiral hinge states in three-dimensional second-order topological insulators (3DSOTIs), resulting in a qu…
Linear level repulsions near exceptional points of non-Hermitian systems
C. Wang, X. R. Wang
The nearest-neighbor level-spacing distributions are a fundamental quantity of disordered systems and universal. It is well-known that extended and localized states of random Hermi…
Hermitian chiral boundary states in non-Hermitian topological insulators
C. Wang, X. R. Wang
Eigenenergies of a non-Hermitian system without parity-time symmetry are complex in general. Here, we show that the chiral boundary states of higher-dimensional (two-dimensional an…
Disorder-Induced Quantum Phase Transitions in Three-Dimensional Second-Order Topological Insulators
C. Wang, X. R. Wang
Disorder effects on three-dimensional second-order topological insulators (3DSOTIs) are investigated numerically and analytically. The study is based on a tight-binding Hamiltonian…
