Hubble-induced phase transitions in the Standard Model and beyond
Javier Rubio, Giorgio Laverda
We review the dynamics of spectator scalar fields non-minimally coupled to gravity in the post-inflationary Universe, with particular emphasis on scenarios where the end of inflati…

Higgs-Induced Gravitational Waves: the Interplay of Non-Minimal Couplings, Kination and Top Quark Mass
Giorgio Laverda, Javier Rubio
We explore a minimal scenario where the sole Standard-Model Higgs is responsible for reheating the Universe after inflation, produces a significant background of gravitational wave…

Ephemeral Oscillons in Scalar-Tensor Theories: The Higgs-like case
Matteo Piani, Javier Rubio, Francisco Torrenti
We investigate the post-inflationary evolution of a non-minimally coupled inflaton field in scalar-tensor theories, framed within the flexible framework of Einstein-Cartan gravity.…
