Cosmic strings are predicted by many field-theory models, and may have been formed at a
symmetry-breaking transition early in the history of the universe, such as that associated with …

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 …

We examine which information on the early cosmological history can be extracted from the
potential measurement by third-generation gravitational-wave observatories of a stochastic …

In the last decade methods and techniques based on supersymmetry have provided deep
insights in quantum chromodynamics and other non-supersymmetric gauge theories at …

We clarify relations among topological solitons in various dimensions: a domain wall, non-
Abelian vortex, magnetic monopole, and Yang-Mills instanton, together with a (non-Abelian) …

We investigate the collision dynamics of two non-Abelian vortices and find that, unlike
Abelian vortices, they neither reconnect themselves nor pass through each other, but create …

Spectra of the stochastic gravitational wave backgrounds from cosmic strings are calculated
and compared with present and future experimental limits. Motivated by theoretical …

A bstract We find that a Z-string is stable in a wide range of parameter space of the two
Higgs doublet model due to a split into a pair of two topological Z-strings with fractional Z …

The most fundamental strings in high-density color superconductivity are the non-Abelian
semisuperfluid strings which have color-gauge flux tubes but behave as superfluid vortices …

We study Bogomol'nyi-Prasad-Sommerfield (BPS) non-Abelian semilocal vortices in U (NC)
gauge theory with NF flavors, NF> NC, in the Higgs phase. The moduli space for an arbitrary …
