Singular gauges and dS invariance of the graviton vacuum
Speaker(s): Donald Marolf
Abstract: There has been a long-running discussion as to whether free gravitons on dS have a dS-invariant state. On the one hand, de Sitter invariant states are clearly singular in gauges favored by cosmologists; e.g. transverse traceless synchronous gauge associated with the k=0 slicing of dS. However, Higuc... read more

Unitarity and Holography in Gravitational Physics
Speaker(s): Donald Marolf
Abstract: Because the gravitational Hamiltonian is a pure boundary term on-shell, asymptotic gravitational fields store information in a manner not possible in local field theories. Two properties follow from this purely gravitational behavior. The first, 'Boundary Unitarity,' holds under AdS-like boundary co... read more
