Talk Title: "Localizing gravity on branes in infinite spaces"

Abstract:

Attempts to achieve a localization of gravity on a braneworld hypersurface embedded in an infinite transverse spacetime have fallen short of what might be desired, for various reasons. There have even been no-go theorems claiming the impossibility of localizing constructions made using just accepted elements of string or M theory. The talk will present a resolution of this problem based upon a hyperbolic solution of type IIA theory and a superposed NS-5 brane. Gravity is bound to the brane surface owing to the existence of a single normalizable bound state of the transverse space Laplacian. The existence of this bound state is related to an asymptotic conformal symmetry in the related Schrödinger problem, a structure that has a history in quantum mechanics going back to the 1950s.
