Time-dependent Features in the Primordial Power Spectrum

Not scheduled

Major conference room (Convention Centre by the Observatory)

Speaker

Mr Simone Dresti (Georg-August University Göttingen)

Description

In a Quantum Field Theory with a time-dependent background time-translational symmetry is broken. We therefore expect renormalization to lead to time-dependent loop corrections. In my talk I will discuss the first order corrections to the power spectrum and the time-dependence that we observe.
