Early universe dynamics: from preheating to gravitational wave spectroscopy

Large Seminar Room

This talk will review the physics of preheating, namely the end of the initial inflationary era of our universe. This period is dominated by highly non-linear  but classical physics, which needs to be studied by dedicated numerical simulations. After discussing such simulations, I will present original results about gravitational waves emitted during preheating. In particular, I will show how they can provide an example where gravitational waves can be used to learn about the particle content of the underlying fundamental theory.
