Brief History of Ultra-light Scalar Dark Matter Models [PDF]
This is a review on the brief history of the scalar field dark matter model also known as fuzzy dark matter, BEC dark matter, wave dark matter, or ultra-light axion. In this model ultra-light scalar dark matter particles with mass m = O(10-22)eV condense

Unified Description of Dark Energy and Dark Matter within the Generalized Hybrid Metric-Palatini Theory of Gravity [PDF]
The generalized hybrid metric-Palatini theory of gravity admits a scalar-tensor representation in terms of two interacting scalar fields. We show that, upon an appropriate choice of the interaction potential, one of the scalar fields behaves like dark ...

Effects of dark matter on the spontaneous scalarization in neutron stars [PDF]
Dark matter, an important portion of compact objects, can influence different phenomena in neutron stars. The spontaneous scalarization in the scalar-tensor gravity has been proposed for neutron stars.

Strong Lensing with Finite Temperature Scalar Field Dark Matter [PDF]
We investigate the gravitational constraints imposed to dark matter halos in the context of finite temperature scalar field dark matter. We find constraints to produce multiple images by dark matter only, we show that there are differences with respect to the full Bose Einstein condensate halo when the temperature of the scalar field in dark matter ...

A model for a non-minimally coupled scalar field interacting with dark matter [PDF]
In this work we investigate the evolution of a Universe consisted of a scalar field, a dark matter field and non-interacting baryonic matter and radiation. The scalar field, which plays the role of dark energy, is non-minimally coupled to space-time curvature, and drives the Universe to a present accelerated expansion.

The continuous tower of scalar fields as a system of interacting dark matter–dark energy [PDF]
This paper aims to introduce a new parameterisation for the coupling Q in interacting dark matter and dark energy models by connecting said models with the Continuous Tower of Scalar Fields model.

Scalar Field Dark Matter [PDF]
This work is a review of the last results of research on the Scalar Field Dark Matter model of the Universe at cosmological and at galactic level. We present the complete solution to the scalar field cosmological scenario in which the dark matter is modeled by a scalar field $\Phi$ with the scalar potential $V(\Phi)=V_{0}(cosh {(\lambda \sqrt{\kappa_{0}

Short review of the main achievements of the scalar field, fuzzy, ultralight, wave, BEC dark matter model [PDF]
The Scalar Field Dark Matter model has been known in various ways throughout its history; Fuzzy, BEC, Wave, Ultralight, Axion-like Dark Matter, etc. All of them consist in proposing that dark matter of the universe is a spinless field Φ that follows the ...

Brief Review on Scalar Field Dark Matter Models
The existence of dark matter in the universe has been solidly established in the last decades, after the arrival of accurate cosmological and astrophysical observations, and some consider it the most challenging problem in modern physics.

Effective field theory and scalar triplet dark matter
We discuss an extension of the standard model with a real scalar triplet, T, including non-renormalizable operators (NROs) up to d = 6. If T is odd under a Z 2 symmetry, the neutral component of T is a good candidate for the dark matter (DM) of the ...
