A conventional topological insulator (TI) has gapped bulk states but gapless edge states.
The emergence of the gapless edge states is dictated by the bulk topological invariant of the …

Pursuing topological phases in natural and artificial materials is one of the central topics in
modern physical science and engineering. In classical magnetic systems, spin waves (or …

We investigate higher-order Weyl semimetals (HOWSMs) having bulk Weyl nodes attached
to both surface and hinge Fermi arcs. We identify a new type of Weyl node, which we dub a …

We investigate disorder-driven topological phase transitions in quantized electric
quadrupole insulators in two dimensions. We show that chiral symmetry can protect the …

Coexisting density-wave and superconducting states along with the large anomalous Hall
effect in the absence of local magnetism remain intriguing and enigmatic features of the …

We analyze the impacts of crystalline symmetry on non-Hermitian skin effects. Focusing on
mirror symmetry, we propose another type of skin effect, a mirror skin effect, which results in …

The topological property of a gapped odd-parity superconductor is jointly determined by its
pairing nodes and Fermi surfaces in the normal state. We reveal that the contractibility of …

Topological physics has been extensively studied in different kinds of bosonic and
Fermionic systems, but the coexistence of topological phonons and electrons in one single …

We study interaction-induced Mott insulators, and their topological properties in a one-
dimensional non-Hermitian strongly correlated spinful fermionic superlattice system with …
