Laura Covi, Simone Dresti
In a Quantum Field Theory with a time-dependent background, time-translational symmetry is broken. We therefore expect time-dependent loop corrections to cosmological observables a…

Renormalization of Composite Operators in time-dependent Backgrounds
Simone Dresti, Antonio Riotto
We study the phenomenon of composite operator renormalization and mixing in systems where time-translational invariance is broken and the evolution is out-of-equilibrium. We show t…
