On the Universality of Hawking Radiation
Sean Gryb, Patricia Palacios, Karim Thébault
A physically consistent semi-classical treatment of black holes requires universality arguments to deal with the `trans-Planckian' problem where quantum spacetime effects appear to…
On the Empirical Consequences of the AdS/CFT Duality
Radin Dardashti, Richard Dawid, Sean Gryb +1
We provide an analysis of the empirical consequences of the AdS/CFT duality with reference to the application of the duality in a fundamental theory, effective theory and instrumen…
Bouncing Unitary Cosmology II: Mini-Superspace Phenomenology
Sean Gryb, Karim P. Y. Thébault
A companion paper provides a proposal for cosmic singularity resolution based upon general features of a bouncing unitary cosmological model in the mini-superspace approximation. T…
Bouncing Unitary Cosmology I: Mini-Superspace General Solution
Sean Gryb, Karim P. Y. Thébault
We offer a new proposal for cosmic singularity resolution based upon a quantum cosmology with a unitary bounce. This proposal is illustrated via a novel quantization of a mini-supe…
Superpositions of the cosmological constant allow for singularity resolution and unitary evolution in quantum cosmology
Sean Gryb, Karim P. Y. Thébault
A novel approach to quantization is shown to allow for superpositions of the cosmological constant in isotropic and homogeneous mini-superspace models. Generic solutions featuring…
