Seminar
Higher Spin de Sitter Hilbert Space
Dr Dionysios Anninos
Delta Institute for Theoretical Physics
2 Feb 2018 (Friday)
4:00 pm
IAS4042, 4/F, Lo Ka Chung Building, Lee Shau Kee Campus, HKUST
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.
The seminar is free and open to the public. No registration is required. Seating is on a first come, first served basis.
