The Homogeneous Scalar Field and the Wet Dark Sides of the Universe
Alberto Diez-Tejedor, Alexander Feinstein
We study the possibility that a generalised real scalar field minimally coupled to gravity could explain both the galactic and the cosmological dark components of the universe. Wit…

Accelerating Universes from Short-Range Interactions
Alberto Diez-Tejedor, Alexander Feinstein
We show that short-range interactions between the fundamental particles in the universe can drive a period of accelerated expansion. This description fits the early universe. In th…

Relativistic hydrodynamics with sources for cosmological K-fluids
Alberto Diez-Tejedor, Alexander Feinstein
We consider hydrodynamics with non conserved number of particles and show that it can be modeled with effective fluid Lagrangians which explicitly depend on the velocity potentials…
