Topological materials promise new functionalities, which are revealed with the help of angle‐
resolved photoemission. Herein, the search for the magnetic bandgap at the Dirac point as a …

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 …

Topological semimetals in three-dimensions (eg, a Weyl semimetal) can be built by stacking
two-dimensional topological phases. The interesting aspect of such a construction is that …

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 …

Berry phase physics is closely related to a number of topological states of matter. Recently
discovered topological semimetals are believed to host a nontrivial π Berry phase to induce …

Multi-Weyl semimetals are new types of Weyl semimetals which have anisotropic nonlinear
energy dispersion and a topological charge larger than one, thus exhibiting a unique …

Weyl semimetals are a three-dimensional topological phase of matter with isolated band
touchings in the Brillouin zone. These points have an associated chirality, and many of the …

We investigate higher-order Weyl semimetals (HOWSMs) having bulk Weyl nodes attached
to both surface and hinge Fermi arcs. We identify a new type of Weyl node, which we dub a …

Topological physics and strong electron–electron correlations in quantum materials are
typically studied independently. However, there have been rapid recent developments in …
