Hubble-induced phase transitions: Walls are not forever
Dario Bettoni, Javier Rubio
The interplay between non-minimally coupled scalar fields and a kinetic-dominated era following the end of inflation triggers the spontaneous symmetry breaking of internal symmetri…
Primordial dark matter halos from fifth forces
Stefano Savastano, Luca Amendola, Javier Rubio +1
We argue that primordial dark matter halos could be generated during radiation domination by long range attractive forces stronger than gravity. In this paper we derive the conditi…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
Preheating in Palatini Higgs inflation
Javier Rubio, Eemeli S. Tomberg
We study the details of preheating in Palatini Higgs inflation. We show, that contrary to what happens in the metric formulation of the model, the Universe does not reheat through…
