We present a self-dual parity-invariant U (1)× U (1) Maxwell-Chern-Simons scalar QED 3.
We show that the energy functional admits a Bogomol'nyi-type lower bound, whose …

This paper deals with vortices in Maxwell-Chern-Simons models with nonminimal coupling.
We introduce constraints between the functions that govern the model and find the …

We study a spontaneously broken SU (2) Chern-Simons-Higgs model coupled though a
Higgs portal to an uncharged triplet scalar with a vacuum state competing with the Higgs …

We study a U (1)× U (1) gauge theory discussing its vortex solutions and supersymmetric
extension. In our set-up, the dynamics of one of two Abelian gauge fields is governed by a …

We report on a new topological vortex solution in U (1)× U (1) Maxwell-Chern-Simons
theory. The existence of the vortex is envisaged by analytical means, and a numerical …

A bstract We study\(\mathcal {N}= 2\) Chern-Simons-matter theories with gauge group\({U} _
{k_1}(1)\times {U} _ {k2}(1)\). We find that, when k 1+ k 2= 0, the partition function computed …

We study a model in d= 2+ 1 space-time dimensions with two sectors. One of them, which
can be considered as the visible sector, contains just a U (1) gauge field which acts as a …

A bstract In this paper we study a 2+ 1 dimensional system in which fermions are coupled to
the self-dual topological vortex in U (1)× U (1) Chern-Simons theory, where both U (1) gauge …

In this paper, we study a system of elliptic equations in ${\mathbb {R}}^{2} $ which arises
from the abelian Chern–Simons–Higgs theory and its $\mathcal {N}= 2$ SUSY extension …

Part I of this thesis is devoted to a brief introduction of vortices in the paradigmatic scenario
of the 3-dimensional Abelian-Maxwell-Higgs model, followed by a short presentation of the …
