The eigenmodes for spinor quantum field theory in global de Sitter space-time

Abstract: The de Sitter space-time is famous for being able to describe an expanding Universe and thus understanding physics in this space-time is of high importance. It is known that N-dimensional de Sitter space-time can be viewed as an ``analytic continuation'' of the N-dimensional sphere. Hence, given the solutions of the Dirac equation on the N-dimensional sphere, one can obtain the solutions of the Dirac equation in de Sitter space-time by using appropriate techniques. In this talk, I will briefly explain how one can construct a spinor quantum field theory in de Sitter space-time by making use of these techniques. This talk is based on arxiv.org/abs/2011.07875 .
