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 …

Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

The Hall effect occurs only in systems with broken time-reversal symmetry, such as materials
under an external magnetic field in the ordinary Hall effect and magnetic materials in the …

Quantum materials hosting Weyl fermions have opened a new era of research in condensed
