Generalized Non-Minimal Derivative Coupling: Application to Inflation and Primordial Black Hole Production
Ioannis Dalianis, Stelios Karydas, Eleftherios Papantonopoulos
We introduce inflationary models where the inflaton features a field dependent non-minimal derivative coupling to the Einstein tensor, that we name GNMDC. This Horndeski term gives…
PBH remnants as dark matter produced in thermal, matter and runaway-quintessence post-inflationary scenarios
Ioannis Dalianis, George Tringas
We investigate the cosmology of mini Primordial Black Holes (PBHs) produced by large density perturbations. The mini PBHs evaporate promptly in the early universe and we assume tha…
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)…
Features and implications of the plateau inflationary potentials
Ioannis Dalianis
After the last PLANCK CMB data the plateau inflationary potentials are favored. I give some examples of such inflationary models emphasizing particularly on the Starobinsky model a…
Non-minimal derivative couplings and inflation in supergravity
Ioannis Dalianis, Fotis Farakos
In this article we motivate and review the embedding of the gravitationally enhanced friction mechanism in supergravity. The very interesting feature is that inflationary models wh…
