The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

We investigate the thermodynamics of a photon gas in an effective field theory model that
describes Lorentz violations through dimension-five operators and Horava–Lifshitz theory …

A model for an expanding noncommutative acoustic fluid analogous to a Friedmann-
Robertson-Walker geometry is derived. For this purpose, a noncommutative Abelian Higgs …

The glueballs lead to gluon and QCD monopole condensations as by‐products of color
confinement. A color dielectric function G (∣ ϕ∣) coupled with a Abelian gauge field is …

We study the thermodynamics of a scalar field on a noncommutative disc implementing the
boundary as the limit case of an interaction with an appropriately chosen confining …

It is well known in the literature that vacuum fluctuations can induce a random motion of
particles which is sometimes called quantum Brownian motion or quantum stochastic …

The theory of quantum gravity (QG) still eludes us. To start with, it is not even clear if gravity
can be quantized like the rest of the fundamental interactions in Nature. For instance, gravity …

In this paper we consider a two-component scalar field theory, with noncommutativity in its
conjugate momentum space. We quantize such a theory in a compact space with the help of …

This thesis is intended to contribute to the long standing problems associated with
theoretical QCD theory. We aim at touching on all possible QCD features such as; color …

As observações de Robert Brown (1828) sobre o movimento aleatório dos grãos de pólen
marcaram o início do fenômeno hoje conhecido por Movimento Browniano, o qual refere-se …
