GAnG Seminar: Alan Rios Fukelman  Centre for Geometry, Analysis and Gravitation Title: de Sitter Universes Abstract: In this talk I will discuss features of Quantum Field Theories in a fixed de Sitter background. I will present an exactly solvable model and show how to obtain all loops correlation functions of local operators. I will then discuss the existence of charged vacuum states in the theory and its relation to spontaneous symmetry breaking in de Sitter spacetimes.
