Topological phases of matter are usually realized in deconfined phases of gauge theories.
In this context, confined phases with strongly fluctuating gauge fields seem to be irrelevant to …

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 …

In this paper, we try to understand the pseudogap phenomenon observed in the cuprate
superconductor through a model study. Specifically, we explore the so-called low …

In this work, we propose a parity-invariant Maxwell–Chern–Simons U (1)× U (1) model
coupled with two charged scalar fields in 2+ 1 dimensions, and show that it admits finite …

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 …

We present a quantum field theoretic description on the t–J model on a square lattice with
dilute holes (ie near half-filling), based on the compact mutual Chern–Simons gauge theory …

In the first part of this thesis, we present a finite-energy electroweak monopole solution
obtained by considering non-linear extensions in the electroweak sector. We find constraints …
