Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

Topological quantum materials (TQMs) have symmetry-protected band structures with useful
electronic properties that have applications in information, sensing, energy and other …

Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …

Dirac and Weyl semimetals both exhibit arc-like surface states. However, whereas the
surface Fermi arcs in Weyl semimetals are topological consequences of the Weyl points …

The zero‐magnetic‐field nonlinear Hall effect (NLHE) refers to the second‐order transverse
