The idea of stable, localized bundles of energy has strong appeal as a model for particles. In
the 1950s, John Wheeler envisioned such bundles as smooth configurations of …

Scalar fields have played an important role in the development of the fundamental theories
of physics as well as in other branches of physics such as gravitation and cosmology. For a …

We provide a detailed analysis of how bosonic dark matter “condensates” interact with
compact stars, extending significantly the results of a recent Letter. We focus on bosonic …

The nature of one of the fundamental components of the Universe, dark matter, is still
unknown. One interesting possibility is that dark matter could exist in the form of a self …

If dark matter is composed of massive bosons, a Bose–Einstein condensation process must
have occurred during the cosmological evolution. Therefore galactic dark matter may be in a …

We consider the Jeans instability and the gravitational collapse of the rotating Bose–Einstein
condensate dark matter halos, described by the zero temperature non-relativistic Gross …

We study the role of temperature and magnetic field on the equation of state and
macroscopic properties of Bose-Einstein condensate stars. These compact objects are …

Using recently developed nonrelativistic numerical simulation code, we investigate the
stability properties of compact astrophysical objects that may be formed due to the Bose …

We determine the k-essence Lagrangian of a relativistic barotropic fluid. The equation of
state of the fluid can be specified in different manners depending on whether the pressure is …

The possibility that dark matter may be in the form of a Bose-Einstein Condensate (BEC) has
been extensively explored at galactic scale. In particular, good fits for the galactic rotations …
