Leading gravitational dressing of operators and states in de Sitter space
Steven B. Giddings, Zi-Yue Wang
We describe construction of gravitationally dressed observables in de Sitter (dS) space, to leading non-trivial order in Newton's constant. We show that for an underlying field the…
Deriving effective descriptions and signal predictions for dynamical gravitational systems
Steven B. Giddings, Madhur Mehta
We investigate top-down derivations of effective descriptions of radiation from gravitational systems such as binaries. With a specified cutoff prescription, one can derive worldli…
Gravitational dressing: from the crossed product to more general algebraic and mathematical structure
Steven B. Giddings
The crossed product, and consequent transition from von Neumann algebras of type III to II, is recovered from a truncation of more general gravitational dressing constructions, abo…
Challenges for describing unitary evolution in nontrivial geometries: pictures and representations
Steven B. Giddings, Julie Perkins
Description of evolution between spatial slices in a general spacetime suffers from a significant difficulty: the states on the slices, in a given basis, are not related by a unita…
Quantum gravity observables: observation, algebras, and mathematical structure
Steven B. Giddings
The questions of describing observables and observation in quantum gravity appear to be centrally important to its physics. A relational approach holds significant promise, and a c…
The unitarity crisis, nonviolent unitarization, and implications for quantum spacetime
Steven B. Giddings
This contribution overviews the information paradox, or perhaps more aptly "unitarity crisis," and a proposed resolution called nonviolent unitarization. It begins by examining the…
