I presented our latest work at the online King’s College London Theoretical Physics Journal Club.

“Some of the unintuitive features of de Sitter”

We would like to study the late time properties of scalar fields on de Sitter, in terms of operators at the late time boundary. In this talk we will start by introducing these late time operators and recognizing them as unitary irreducible representations of SO(d+1,1), the symmetry group of d+1 dimensional de Sitter. We will discuss their inner products and two point functions where there exist subtle differences between handling light and heavy fields.
