Multicomponent superconductivity is realized in multiband superconductors when an
interband pairing interaction is considerably weaker than the intraband interactions. There is …

This article reviews theoretical and experimental work on the novel physics in multiband
superconductors. Multiband superconductors are characterized by multiple superconducting …

It is shown that under certain conditions, three-component superconductors (and, in
particular, three-band systems) allow stable topological defects different from vortices. We …

In contrast to single-component superconductors, which are described at the level of
Ginzburg-Landau theory by a single parameter κ and are divided in type-I κ< 1/2 and type-II …

We show that two-band superconductors harbor hidden criticality deep in the
superconducting state, stemming from the critical temperature of the weaker band taken as …

A procedure to derive the Ginzburg-Landau (GL) theory from the multiband BCS
Hamiltonian is developed in a general case with an arbitrary number of bands and arbitrary …

When two graphene sheets are twisted relative to each other by a small angle, enhanced
correlations lead to superconductivity whose origin remains under debate. Here, we derive …

Chiral d-wave superconductivity has been proposed in a number of different materials, but
characteristic experimental fingerprints have been largely lacking. We show that quadruply …

Chiral d-wave superconductivity has recently been proposed in a wide range of materials
based on both experiment and theoretical studies. Chiral superconductors host a finite …

Observability of half-quantum vortices and skyrmions in p-wave superconductors is an
outstanding open question. Under the most common conditions, fractional flux vortices are …
