We review our recent work on solitons in the Higgs phase. We use U (NC) gauge theory with
NF Higgs scalar fields in the fundamental representation, which can be extended to possess …

A bstract Chiral magnets with the Dzyaloshinskii-Moriya (DM) interaction have received
quite an intensive focus in condensed matter physics because of the presence of a chiral …

We consider theories consisting of a planar interface with N= 4 super-Yang–Mills on either
side and varying gauge coupling across the interface. The interface does not carry any …

We investigate vortices on a cylinder in supersymmetric non-Abelian gauge theory with
hypermultiplets in the fundamental representation. We identify moduli space of periodic …

A systematic method to obtain the effective Lagrangian on the Bogomol'nyi-Prasad-
Sommerfield background in supersymmetric gauge theories is worked out, taking domain …

We show that sine-Gordon solitons appear in the low-energy effective theory of a domain
wall in a U (1) gauge theory with two charged complex scalar fields with masses if we …

We classify bions in the Grassmann sigma model (including the model) on with twisted
boundary conditions. We formulate these models as gauge theories with flavors in the …

We systematically classify 1/2, 1/4 and 1/8 BPS equations in SUSY gauge theories in d= 6,
5, 4, 3 and 2 with eight supercharges, with gauge groups and matter contents being …

We construct a molecule of fractional vortices with fractional topological lump charges as a
baby Skyrmion with the unit topological lump charge in the antiferromagnetic (or XY) baby …

Domain walls in U (N) gauge theories, coupled to Higgs scalar fields with degenerate
masses, are shown to possess normalizable non-Abelian Nambu-Goldstone (NG) modes …
