Advances in High Energy Physics, 2017 We investigate matter creation processes during the reheating period of the early Universe, by using the thermodynamic of open systems. The Universe is assumed to consist of the inflationary scalar field, which, through its decay, generates relativistic ...

A Further Analysis of a Cosmological Model of Quintessence and Scalar Dark Matter [PDF]
Phys.Rev. D63 (2001) 063506, 2000 We present the complete solution to a 95% scalar field cosmological model in which the dark matter is modeled by a scalar field $\Phi$ with the scalar potential $V(\Phi)=V_{o}[ \cosh {(\lambda \sqrt{\kappa_{o}}\Phi)}-1]$ and the dark energy is modeled by a scalar field $\Psi$, endowed with the scalar potential $\tilde{V}(\Psi)=\tilde{V_{o}}[ \sinh ...

Structure formation with scalar field dark matter: the field approach [PDF]
Journal of Cosmology and Astroparticle Physics, 2012 We study the formation of structure in the Universe assuming that dark matter can be described by a scalar field $\tilde $ with a potential $V( )=-\mathfrak{m}^{2}\tilde ^{2}/2+ \tilde ^4/4$. We derive the evolution equations of the scalar field in the linear regime of perturbations.

European Physical Journal C: Particles and Fields, 2021 We consider a cosmological scenario endowed with an interaction between the universe’s dark components – dark matter and dark energy. Specifically, we assume the dark matter component to be a pressure-less fluid, while the dark energy component is a ...

Study of rotation curves of spiral galaxies with a scalar field dark matter model [PDF]
AIP Conf. Proc. 1473, 74 (2012), 2012 In this work we study rotation curves of spiral galaxies using a model of dark matter based on a scalar-tensor theory of gravity. We show how to estimate the scalar field dark matter parameters using a sample of observed rotation curves.

The quantum character of the Scalar Field Dark Matter
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT The scalar field dark matter (SFDM) model, also called Fuzzy, Wave, Bose–Einstein, and Ultra-light Dark Matter, has received a lot of attention because it has been able to provide simpler and more natural explanations for various features of galaxies, such as the number of satellite galaxies and the cusp-core problem.

Journal of High Energy Physics, 2021 We propose a new mechanism to communicate between fermion dark matter and the Standard Model (SM) only through the four-form flux. The four-form couplings are responsible for the relaxation of the Higgs mass to the correct value and the initial ...
