Galactic collapse of scalar field dark matter [PDF]
Classical and Quantum Gravity, 2002 We present a scenario for galaxy formation based on the hypothesis of scalar field dark matter. We interpret galaxy formation through the collapse of a scalar field fluctuation.

Short review of the main achievements of the scalar field, fuzzy, ultralight, wave, BEC dark matter model [PDF]
Frontiers in Astronomy and Space Sciences, 2023 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 ...

Scalar field dark matter and the Higgs field [PDF]
Physics Letters B, 2016 We discuss the possibility that dark matter corresponds to an oscillating scalar field coupled to the Higgs boson. We argue that the initial field amplitude should generically be of the order of the Hubble parameter during inflation, as a result of its ...

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.

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 ...

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 ...

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.

Brief History of Ultra-light Scalar Dark Matter Models [PDF]
EPJ Web of Conferences, 2018 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

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,
