Newtonian collapse of scalar field dark matter [PDF]
Physical Review D, 2003 In this letter, 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 Einstein-Klein-Gordon, is reduced to the Schr dinger-Newton one in the weak field limit. The scaling symmetries of the SN equations are

Oscillating scalar-field dark matter in supergravity [PDF]
Journal of High Energy Physics, 2001 We show that an oscillating scalar field in supergravity of mass of the order of $\sim$ TeV with a nonzero vacuum expectation value ($\sim 10^{10}$ GeV) can be a candidate of cold dark matter (CDM). To avoid the gravitino problem, we need a low reheating temperature after the primordial inflation.

How the Scalar Field of Unified Dark Matter Models Can Cluster [PDF]
, 2008 We use scalar-field Lagrangians with a non-canonical kinetic term to obtain unified dark matter models where both the dark matter and the dark energy, the latter mimicking a cosmological constant, are described by the scalar field itself.

Resonant SIMP dark matter [PDF]
Physics Letters B, 2016 We consider a resonant SIMP dark matter in models with two singlet complex scalar fields charged under a local dark U(1)D. After the U(1)D is broken down to a Z5 discrete subgroup, the lighter scalar field becomes a SIMP dark matter which has the ...

A model for a non-minimally coupled scalar field interacting with dark matter [PDF]
, 2005 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 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.

Scalar Field Dark Matter, Cross Section and Planck-Scale Physics [PDF]
, 2000 In recent papers we have proposed that the dark matter of the Universe could be from scalar field origin. In this letter, we find that if the scale of renormalization of the model is of order of the Planck Mass, then a scalar field $\Phi $ endowed with ...

Testing the mean field theory of scalar field dark matter
SciPost Physics Proceedings, 2023 Scalar field dark matter offers an interesting alternative to the traditional WIMP dark matter picture. Astrophysical and cosmological simulations are useful to constraining the mass of the dark matter particle in this model. This is particularly true at

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