We report microscopic solutions for vortices carrying a variable fraction of magnetic flux quantum and domain walls in a three-band $s+is$ superconductor and investigate their properties. The solutions are obtained in a fully self-consistent treatmen

Magnetic field is expelled from a superconductor, unless it forms quantum vortices, consisting of a core singularity with current circulating around it. The London quantization condition implies that there is one core singularity per quantum of magne

While the properties of standard (single-component) superfluids are well understood, principal differences arise in a special type of multicomponent systems -- the so-called Borromean supercounterfluids -- in which (i) supertransport is possible only

It has been proposed that two-band superconductors exhibit a distinct phase characterized by two correlation lengths, where one is smaller and the other larger than the magnetic field penetration length. This regime was coined type-1.5 superconductiv

Recent experiments have pointed to the formation of a new state of matter, the electron quadrupling condensate in Ba$_{1-x}$K$_x$Fe$_2$As$_2$ . The state spontaneously breaks time-reversal symmetry and is sandwiched between two critical points, separ

The recent experiments reported observation of a state with symmetry-breaking appearing at the level of four-electron order parameter (electronic quadruplets condensation) in a multicomponent system. This is in contrast to the conventional case where

We consider a new class of topological defects in chiral magnetic crystals such as FeGe and MnSi. These are composite topological defects that arise when skyrmions in the magnetic order intersect with twin boundaries in the underlying crystalline lat

Counterflow superfluidity in a system with $N\geq 3$ components is distinctively different from the $N=2$ case. The key feature is the difference between the number ($N$) of elementary vortex excitations and the number ($N-1$) of independent branches

We predict a topological defect in ferroelectric barium titanate which we call a skyrme line. These are line-like objects characterized by skyrmionic topological charge. As well as configurations with integer charge, the charge density can split into

We describe the formation of swift heavy ion tracks in polyethylene (PE) by combining the Monte Carlo code TREKIS, which models electronic excitation in nanometric proximity of the ion trajectory, with the molecular dynamics simulating a response of
