Self-interacting complex scalar field as dark matter
AIP Conference Proceedings, 2011We study the viability of a a complex scalar field χ with self‐interacting potential V = m0χ/2|χ|2+h|χ|4 as dark matter. Due to the self interaction, the scalar field forms a Bose‐Einstein condensate at early times that represents dark matter. The self interaction is also responsible of quantum corrections to the scalar field mass that naturally give ...

Structure Formation with Scalar Field Dark Matter
AIP Conference Proceedings, 2010In this work we calculate the different ingredients needed to obtain the matter density profile of the large‐scale structure we observe now a days in a qualitative way. The key difference of the work lays on the fact that we study the formation of structure in the Universe assuming that dark matter can be described by a scalar field (SF) Φ with a ...

The massless scalar field as an alternative to dark matter
Astronomical & Astrophysical Transactions, 1997Abstract It is shown that if the scalar gravitational field in the generalized scalar—tensor theory of gravitation is taken into account, the cosmological requirement for the existence of dark matter is less strong.

A complex-scalar-field model for dark matter
EPL (Europhysics Letters), 2010As a consequence of the global definition for the cosmological constant Λ, the empirical relation Λ 2.7κρ0 (with ρ0 the density of all matter and radiation) implies that a stringent condition must be satisfied by the Lagrangian for the non-baryonic (dominant) component of dark matter.
