Talk Title: Quantum evolution (and entanglement) during inflation

Abstract: In this talk, I will discuss inflation as an open quantum system and derive quantum corrections to cosmological observables, such as the power spectrum, showing explicitly why it is important to go beyond standard (Wilsonian) effective field theory. I will highlight deep insights this approach provides regarding quantum entanglement in the early universe and emphasize the features which apply to other gravitational systems.
