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 ...

Unified Dark Matter Scalar Field Models [PDF]
Advances in Astronomy, 2010 We analyze and review cosmological models in which the dynamics of a single scalar field accounts for a unified description of the Dark Matter and Dark Energy sectors, dubbed Unified Dark Matter (UDM) models.

Constraints on Scalar Field Dark Matter from Colocated Michelson Interferometers. [PDF]
Physical Review Letters, 2021 Low-mass (sub-eV) scalar field dark matter may induce apparent oscillations of fundamental constants, resulting in corresponding oscillations of the size and the index of refraction of solids.

Dark Matter from Scalar Field Fluctuations. [PDF]
Physical Review Letters, 2019 Dark matter (DM) may have its origin in a pre-big-bang epoch, the cosmic inflation. Here, we consider for the first time a broad class of scenarios where a massive free scalar field unavoidably reaches an equilibrium between its classical and quantum ...

Cosmological constraints on scalar field dark matter [PDF]
International Journal of Modern Physics D, 2015 This paper aims to put constraints on the parameters of the Scalar Field Dark Matter (SFDM) model, when dark matter is described by a free real scalar field filling the whole universe, plus a cosmological constant term.

Galactic collapse of scalar field dark matter [PDF]
Classical and Quantum Gravity, 2001 We present a scenario for core galaxy formation based on the hypothesis of scalar field dark matter. We interpret galaxy formation through the collapse of as calar field fluctuation.

Newtonian Collapse of Scalar Field Dark Matter [PDF]
Physical Review D, 2003 In this paper, we develop a Newtonian approach to the collapse of galaxy fluctuations of scalar field dark matter under initial conditions inferred from simple assumptions. The full relativistic system, the so-called ‘

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 with the real scalar field is modeled by statistical equal-time two-point functions and gravity is treated by two stochastic ...

Sensitivity of Atom Interferometry to Ultralight Scalar Field Dark Matter. [PDF]
Physical Review Letters, 2016 We discuss the use of atom interferometry as a tool to search for dark matter (DM) composed of virialized ultralight fields (VULFs). Previous work on VULF DM detection using accelerometers has considered the possibility of equivalence-principle-violating

Nonrelativistic approach for cosmological scalar field dark matter [PDF]
Physical Review D, 2013 We derive non-relativistic equations of motion for the formation of cosmological structure in a Scalar Field Dark Matter (SFDM) model corresponding to a complex scalar field endowed with a quadratic scalar potential.
