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 …

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

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

Over the past decade, topological materials—in which the topology of electron bands in the
bulk material leads to robust, unconventional surface states and electromagnetism—have …

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 …

Abstract A three-dimensional (3D) topological insulator (TI) is a quantum state of matter with
a gapped insulating bulk yet a conducting surface hosting topologically protected gapless …

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 …

A topological insulator protected by time-reversal symmetry is realized via spin–orbit
interaction-driven band inversion. The topological phase in the Bi1− x Sb x system is due to …

Bi2Te3 is a well-recognized material for its unique properties in diverse thermoelectric
applications near room temperature. The considerable efforts on Bi2Te3-based alloys have …
