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 …

Metal phosphides (MPs) with unique and desirable physicochemical properties provide
promising potential in practical applications, such as the catalysis, gas/humidity sensor …

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 …

Quantum materials hosting Weyl fermions have opened a new era of research in condensed
matter physics. First proposed in 1929 in the context of particle physics, Weyl fermions have …

Topological insulators and topological semimetals are both new classes of quantum
materials, which are characterized by surface states induced by the topology of the bulk …

We investigate the orthorhombic phase (T d) of the layered transition-metal dichalcogenide
MoTe 2 as a Weyl semimetal candidate. MoTe 2 exhibits four pairs of Weyl points lying …

In recent days, study of topological Weyl semimetals have become an active branch of
physics and materials science because they led to realization of the Weyl fermions and …

A Dirac nodal-line semimetal phase, which represents a new quantum state of topological
materials, has been experimentally realized only in a few systems, including PbTaSe 2, PtSn …

Three-dimensional (3D) topological semimetals represent a new class of topological
matters. The study of this family of materials has been at the frontiers of condensed matter …

Weyl semimetals are conductors whose low-energy bulk excitations are Weyl fermions,
whereas their surfaces possess metallic Fermi arc surface states. These Fermi arc surface …
