Spin-orbit coupling in inversion-asymmetric magnetic crystals and structures has emerged
as a powerful tool to generate complex magnetic textures, interconvert charge and spin …

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 with spin-momentum-locked topological surface states are expected
to exhibit a giant spin-orbit torque in the topological insulator/ferromagnet systems. To date …

The three dimensional topological insulator bismuth selenide (Bi 2 Se 3) is expected to
possess strong spin-orbit coupling and spin-textured topological surface states and, thus …

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 …

Topological insulators exhibit metallic surface states populated by massless Dirac fermions
with spin-momentum locking, where the carrier spin lies in-plane, locked at right angles to …

The surface of a topological insulator plays host to an odd number of linearly-dispersing
Dirac fermions, protected against back-scattering by time-reversal symmetry. Such …

The three-dimensional topological insulator is a quantum state of matter characterized by an
insulating bulk state and gapless Dirac cone surface states. Device applications of …

The nonlinear Hall effect due to Berry curvature dipole (BCD) induces frequency doubling,
which was recently observed in time-reversal-invariant materials. Here we report novel …

Surface states of three-dimensional topological insulators exhibit the phenomenon of spin–
momentum locking, whereby the orientation of an electron spin is determined by its …
