Scalar Field Oscillations Contributing to Dark Energy
Eduard Masso, Francesc Rota, Gabriel Zsembinszki
We use action-angle variables to describe the basic physics of coherent scalar field oscillations in the expanding universe. These analytical mechanics methods have some advantages…
On the Gravitational Field of Antimatter
Eduard Masso, Francesc Rota
The gravitational field of matter and that of antimatter could differ. This might be one signature of quantum gravity. We show that primordial Big Bang Nucleosynthesis restricts su…
Primordial Nucleosynthesis as a Test of the Friedmann Equation in the Early Universe
Eduard Massó, Francesc Rota
In the standard hot big bang model, the expansion of the early universe is given by the Friedmann equation with an energy density dominated by relativistic particles. Since in a va…
Primordial Helium Production in a Charged Universe
Eduard Masso, Francesc Rota
We use the constraints arising from primordial nucleosynthesis to bound a putative electric charge density of the universe. We find , four ord…
