Description

We investigate the post-inflationary dynamics of Higgs-Inflation within the framework of Einstein-Cartan gravity, with a particular emphasis on the scalar sector of the theory. Notably, we find that the inflaton potential is capable of supporting the formation of meta-stable non linear structures, which can generate a significant gravitational wave signal, and significantly modify the standard expansion history of the Universe.
