Successful Higgs inflation from combined nonminimal and derivative couplings
Stelios Karydas, Eleftherios Papantonopoulos, Emmanuel N. Saridakis
We propose an inflationary scenario based on the concurrent presence of non-minimal coupling (NMC) and generalized non-minimal derivative coupling (GNMDC), in the context of Higgs…

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…
