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

Very recently, the half-metallic compound Co 3 Sn 2 S 2 was proposed to be a magnetic
Weyl semimetal (WSM) with Weyl points only 60 meV above the Fermi level EF. Owing to the …

The search for topological superconductors (TSCs) is one of the most urgent contemporary
problems in condensed matter systems. TSCs are characterized by a full superconducting …

Three-dimensional topological nodal lines, the touching curves of two bands in momentum
space, which give rise to drumhead surface states, provide an opportunity to explore a …

The recent discovery of the first Weyl semimetal in TaAs provides the first observation of a
Weyl fermion in nature. Such a topological semimetal features a novel type of anomalous …

Weyl semimetals constitute a newly discovered class of three-dimensional topological
materials with linear touchings of valence and conduction bands in the bulk. The most …

When solid state systems possess active orbital-band structures subject to spin-orbit
coupling, their multicomponent electronic structures are often described in terms of effective …

Nodal superconductors without inversion symmetry exhibit nontrivial topological properties,
manifested by topologically protected flat-band edge states. Here we study the effects of …

Noncentrosymmetric superconductors with strong spin-orbit coupling and the B phase of He
3 are possible realizations of topological superconductors with time-reversal symmetry. The …

We study the stability of topologically protected zero-energy flat bands at the surface of
nodal noncentrosymmetric superconductors, accounting for the alteration of the gap near the …
