We study the fate of U(1) strings embedded in a non-Abelian gauge theory with the hierarchical pattern of symmetry breaking $G\mathrm{U}(1)$ nothing, $V\ensuremath{\gg}v.$ While in the low-energy limit the Abrikosov-Nielsen-Olesen string (flux tube) is perfectly stable, when considered in the full theory it is metastable. We consider the simplest example: the magnetic flux tubes in SU(2) gauge theory with adjoint and fundamental scalars. First, the adjoint scalar develops a vacuum expectation…

Non-Abelian string junctions as confined monopoles

Various dynamical regimes associated with confined monopoles in the Higgs phase of $\mathcal{N}=2$ two-flavor QCD are studied. The microscopic model we deal with has the

Non-BPS non-Abelian vortices with 1 internal moduli space are studied in an = 2 supersymmetric U(1) × SU(2) gauge theory with adjoint mass terms. For generic internal orientations the classical force

Effects of extra degrees of freedom on a decay rate of metastable topological objects

We review the recent results on a decay rate of metastable topological configurations such as strings and domain walls. The transition from a state with higher tension to a state with lower one

Closed flux tubes in higher representations and their string description in D=2+1 SU(N) gauge theories

We calculate, numerically, the low-lying spectrum of closed confining flux tubes that carry flux in different representations of SU(N). We do so for SU(6) at β = 171, where the calculated low-energy

Nielsen-Olesen strings in Supersymmetric models

We investigate the behaviour of a model with two oppositely charged scalar fields. In the Bogomol'nyi limit this may be seen as the scalar sector of N = 1 supersymmetric QED, and it has been shown

We discuss general properties and possible types of magnetic vortices in non-Abelian gauge theories (we consider here $G= SU(N), SO(N), USp(2N)$) in the Higgs phase. The sources of such vortices

False vacuum decay

This thesis reviews the exact numerical computation of the classical bounce solution in the false vacuum decay for a quartic scalar field potential which is offset by an external source. The decay
