Topological quantum chemistry and symmetry-based indicators have facilitated large-scale
searches for materials with topological properties at the Fermi energy (EF). We report the …

The past decade has witnessed a surge of interest in exploring emergent particles in
condensed matter systems. Novel particles, emerged as excitations around exotic band …

The field of two-dimensional topological semimetals, which emerged at the intersection of
two-dimensional materials and topological materials, has been rapidly developing in recent …

Higher-order topology yields intriguing multidimensional topological phenomena, while
Weyl semimetals have unconventional properties such as chiral anomaly. However, so far …

Exceptional points (EPs) appear as degeneracies in the spectrum of non-Hermitian matrices
at which the eigenvectors coalesce. In general, an EP of order n may find room to emerge if …

Unlike conventional Weyl nodes, unconventional ones carry a quantized monopole charge
C> 1, and their existence needs the protection of crystalline symmetries in addition to …

This year, Liu et al.[Phys. Rev. B 104, L041405 (2021) 2469-9950 10.1103/PhysRevB. 104.
L041405] proposed another class of topological phonons [TPs, ie, one-nodal surface (NS) …

The unconventional Weyl point with nonlinear dispersion features higher topological charge|
C|> 1 and multiple topologically protected Fermi arc states at its boundary. As a novel …

Unconventional Weyl points (WPs), carrying topological charge 2 or higher, possess
interesting properties different from ordinary charge-1 WPs, including multiple Fermi arcs …

Topological metals (TMs) are a kind of special metallic materials, which feature nontrivial
band crossings near the Fermi energy, giving rise to peculiar quasiparticle excitations. TMs …
