Cosmology of the very early universe
E. Galindo-Dellavalle, G. German, A. de la Macorra
We study cosmological solutions for the very early universe beginning at the Planck scale for a universe containing radiation, curvature and, as a simplification of a possible scal…
Acceptable Inverse Power Law Potential Quintessence with n=18/7
A. de la Macorra, G. German
We present a particle physics quintessence model which agrees well with existing cosmological data, including the position of the acoustic peaks. This model has an inverse power la…
Angular Inflation from Supergravity
G. Germán, Anupam Mazumdar, A. Pérez-Lorenzana
We study supergravity inflationary models where inflation is produced along the angular direction. For this we express the scalar component of a chiral superfield in terms of the r…
Low-scale supergravity inflation with R-symmetry
G. German, A. de la Macorra, M. Mondragon
We study a supergravity model of inflation with R-symmetry and a single scalar field, the inflaton, slowly rolling away from the origin. The scales of inflation can be as low as th…
