This review elaborates pedagogically on the fundamental concept, basic theory, expected
properties, and materials realizations of topological superconductors. The relation between …

Weyl metal is the first example of a conducting material with a nontrivial electronic structure
topology, making it distinct from an ordinary metal. Unlike in insulators, the nontrivial …

Topological superconductors are novel classes of quantum condensed phases,
characterized by topologically nontrivial structures of Cooper pairing states. On the surfaces …

Two noncentrosymmetric ternary pnictides, CaAgP and CaAgAs, are reported as topological
line-node semimetals protected solely by mirror-reflection symmetry. The band gap vanishes …

Topological semimetals are well known for the linear energy band dispersion in the bulk
state and topologically protected surface state with arc-like Fermi surface. The angle …

Weyl semimetals (WSMs) are topologically protected three-dimensional materials whose
low-energy excitations are linearly dispersing massless Dirac fermions, possessing a …

Dirac semimetals host bulk band-touching Dirac points and a surface Fermi loop. We
develop a theory of superconducting Dirac semimetals. Establishing a relation between the …

Topological superconductors have become a subject of intense research due to their
potential use for technical applications in device fabrication and quantum information …

The “hydrogen atom” of magnetic Weyl semimetals, with the minimum number of Weyl
points, has received growing attention recently due to the possible presence of Weyl-related …

We report on a study of intrinsic superconductivity in a Weyl metal, ie, a doped Weyl
semimetal. Two distinct superconducting states are possible in this system in principle: a …
