A bstractWe study vortex-strings in four-dimensional N=2$$ \mathcal{N}=2 $$ supersymmetric SU(Nc) × U(1) gauge theories with Nf hypermultiplets in the fundamental representation of SU(Nc) and general U(1) charges. If Nf> Nc, the vacuum is not gapped and the low-energy theory contains both the vacuum massless excitations and the string zero-modes. The question we address in this work is whether the vacuum and the string moduli decouple at low energies, allowing a description of the low-energy…

A bstractWe study 12$$ \frac{1}{2} $$-BPS vortex-strings in four dimensional N$$ \mathcal{N} $$ = 2 supersymmetric quiver theories with gauge group SU(N)n × U(1). The matter content of the quiver can

Confinement and moduli locking of Alice strings and monopoles

We argue that strings (vortices) and monopoles are confined, when fields receiving nontrivial Aharonov-Bohm (AB) phases around a string develop vacuum expectation values (VEVs). We illustrate this in

Quantizing a solitonic string

Quite often the zero mode dynamics on solitonic vortices are described by a non-conformal effective world-sheet sigma model (WSSM). We address the problem of solitonic string quantization in this



New vortex-string worldsheet theories from supersymmetric localization

A bstractWe use supersymmetric localization techniques to study the low-energy dynamics of BPS vortex-strings in four-dimensional N=2$$ \mathcal{N}=2 $$ theories. We focus on theories with SU(Nc) ×

Effective world-sheet theory for non-Abelian semilocal strings in N=2 supersymmetric QCD

We consider non-Abelian semilocal strings (vortices or vortex strings) arising in $\mathcal{N}=2$ supersymmetric $U(N)$ gauge theory with ${N}_{f}=N+\stackrel{\texttildelow{}}{N}$ matter

Exact results in D = 2 supersymmetric gauge theories

A bstractWe compute exactly the partition function of two dimensional $ \mathcal{N} $ = (2, 2) gauge theories on S2 and show that it admits two dual descriptions: either as an integral over the

Partition Functions of $${\mathcal{N}=(2,2)}$$N=(2,2) Gauge Theories on S2 and Vortices

We apply localization techniques to compute the partition function of a two-dimensional $${\mathcal{N}=(2,2)}$$N=(2,2) R-symmetric theory of vector and chiral multiplets on S2. The path integral

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

On the moduli space of semilocal strings and lumps

We study BPS non-abelian semilocal vortices in U(Nc) gauge theory with Nf flavors, Nf > Nc, in the Higgs phase. The moduli space for arbitrary winding number is described using the moduli matrix
