Higher Spin de Sitter Hilbert Space

Abstract

The Vasiliev theory of a de Sitter space with an infinite tower of interacting massless gauge fields with increasing spin is considered. In this talk, the speaker will propose a quantum completion of the classical theory, by providing the microscopic operator content and Hilbert space. He will also identify the exact Bunch-Davies vacuum state within this Hilbert space as well as a construction of approximate bulk quantum fields in the large N limit. Time permitting, he will comment on the de Sitter entropy from the point of view of his framework.
