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 …

The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

The prediction and realization of topological insulators have sparked great interest in
experimental approaches to the classification of materials,–. The phase transition between …

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 past decade has witnessed an explosion in the field of quantum materials, headlined by
the predictions and discoveries of novel Landau-symmetry-broken phases in correlated …

The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

Three types of fermions play a fundamental role in our understanding of nature: Dirac,
Majorana and Weyl. Whereas Dirac fermions have been known for decades, the latter two …

The topology of the electronic structure of a crystal is manifested in its surface states.
Recently, a distinct topological state has been proposed in metals or semimetals whose spin …

Topological insulators represent a new quantum state of matter which is characterized by
peculiar edge or surface states that show up due to a topological character of the bulk wave …

Abstract Symmetry-broken three-dimensional (3D) topological Dirac semimetal systems with
strong spin-orbit coupling can host many exotic Hall-like phenomena and Weyl fermion …
