HET Seminar | Tom Hartman, Cornell University | "Dynamical Constraints on RG Flows and Cosmology” | Bloomberg Lecture Hall

A free lecture open to the public.

I will discuss time-dependent probes of the renormalization group, and derive new constraints that govern the spread of local operators in holographic theories. The same methods lead to sum rules for inflationary correlators, relating observables, like the speed of sound during inflation, to properties of the UV theory.
