Supplying dark energy from scalar field dark matter [PDF]
International Journal of Modern Physics D, 2018 We consider the hypothesis that dark matter (DM) and dark energy (DE) consist of ultra-light self-interacting scalar particles. It is found that the Klein–Gordon equation with only two free parameters (mass and self-coupling) on a Schwarzschild ...

Scalar field dark matter in hybrid approach [PDF]
Physical Review D, 2017 We develop a hybrid formalism suitable for modeling scalar field dark matter, in which the phase-space distribution associated to the real scalar field is modeled by statistical equal-time two-point functions and gravity is treated by two stochastic ...

Dwarf galaxies in multistate scalar field dark matter halos [PDF]
Physical Review D, 2015 We analyse the velocity dispersion for eight of the Milky Way dwarf spheroidalsatellites in the context of finite temperature scalar field dark mater.

Scalar field dark matter and dark energy: a hybrid model for the dark sector [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 Diverse cosmological and astrophysical observations strongly hint at the presence of dark matter and dark energy in the Universe. One of the main goals of Cosmology is to explain the nature of these two components.

Rotation curves of high-resolution LSB and SPARC galaxies with fuzzy and multistate (ultralight boson) scalar field dark matter [PDF]
, 2017 Cold dark matter (CDM) has shown to be an excellent candidate for the dark matter (DM) of the Universe at large scales, however it presents some challenges at the galactic level. The scalar field dark matter (SFDM), also called fuzzy, wave, Bose-Einstein

Searching for Scalar Field Dark Matter using Cavity Resonators and Capacitors [PDF]
Physical Review D, 2022 We establish new experiments to search for dark matter based on a model of a light scalar field with a dilaton-like coupling to the electromagnetic field, which is strongly motivated by superstring theory.

Cosmological structure formation in scalar field dark matter with repulsive self-interaction: the incredible shrinking Jeans mass [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Scalar Field Dark Matter (SFDM) comprised of ultralight (≳ 10−22 eV) bosons is an alternative to standard, collisionless Cold Dark Matter (CDM) that is CDM-like on large scales but inhibits small-scale structure formation. As a Bose-Einstein condensate,

Core-halo mass relation in scalar field dark matter models and its consequences for the formation of supermassive black holes [PDF]
Physical Review D, 2021 Scalar-field dark matter (SFDM) halos exhibit a core-envelope structure with soliton-like cores and CDM-like envelopes. Simulations without self-interaction (free-field case) report a core-halo mass relation $M_c\propto M_{h}^{\beta}$, with either $\beta=

Searching for Scalar Field Dark Matter with LIGO. [PDF]
Physical Review LettersWe report on a direct search for scalar field dark matter using data from LIGO's third observing run. We analyze the coupling of size oscillations of the interferometer's beam splitter and arm test masses that may be caused by scalar field dark matter ...

The inflaton portal to dark matter [PDF]
Journal of High Energy Physics, 2017 We consider the possibility that the inflaton is part of the dark sector and interacts with the standard model through a portal interaction with a heavy complex scalar field in equilibrium with the standard model at high energies.
