Dense quantum chromodynamic matter accommodates various kind of topological solitons
such as vortices, domain walls, monopoles, kinks, boojums, and so on. In this review, we …

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

There is a soliton in a superconductor having two bands (two-band superconductor), when
the interband interaction is much smaller than the intraband interaction. This soliton is in a …

We investigate the competition between the extended s±-wave and dx 2-y 2-wave pairing
order parameters in the iron-based superconductors. Because of the frustrating pairing …

The effects of the coupling between two electronic condensates in two-gap mesoscopic
superconductors are studied within the Ginzburg-Landau theory using a finite difference …

We report the experimental formation of a fractional vortex generated by using a thin
superconducting bi-layer in the form of a niobium bi-layer, observed as a magnetic flux …

We study the effects of the internal coherent (Rabi) coupling in vortex lattices in two-
component BECs under rotation. We find how the vortex lattices without the Rabi coupling …

We study the Berezinskii-Kosterlitz-Thouless (BKT) transition of two-component Bose
mixtures in two spatial dimensions. When phases of both components are decoupled, half …

We investigate some significant properties of multi-band superconductors. They are time-
reversal symmetry breaking, chirality and fractional quantum flux vortices in three-band …

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