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 …

Topological insulators are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …

An intrinsic magnetic topological insulator (TI) is a stoichiometric magnetic compound
possessing both inherent magnetic order and topological electronic states. Such a material …

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 …

Tetradymites are M 2 X 3 compounds—in which M is a group V metal, usually Bi or Sb, and
X is a group VI anion, Te, Se or S—that crystallize in a rhombohedral structure. Bi 2 Se 3, Bi …

Topology, a mathematical concept, has recently become a popular and truly
transdisciplinary topic encompassing condensed matter physics, solid state chemistry, and …

Topological insulators (TIs) are quantum materials with insulating bulk and topologically
protected metallic surfaces with Dirac-like band structure. The most challenging problem …

Dirac metals (gapless semiconductors) are believed to turn into Weyl metals when
perturbations, which break either time reversal symmetry or inversion symmetry, are …
