Exact Hawking Radiation of Scalars, Fermions, and Bosons Using the Tunneling Method Without Back-Reaction
Alexandre Yale
Hawking radiation is studied for arbitrary scalars, fermions, and spin-1 bosons, using a tunneling approach, to every order in but ignoring back-reaction effects. It is sho…
Gravitational Wave Extraction in Simulations of Rotating Stellar Core Collapse
Christian Reisswig, Christian D. Ott, Ulrich Sperhake +1
We perform simulations of general relativistic rotating stellar core collapse and compute the gravitational waves (GWs) emitted in the core bounce phase of three representative mod…
The 1/N expansion of colored tensor models
Razvan Gurau
In this paper we perform the 1/N expansion of the colored three dimensional Boulatov tensor model. As in matrix models, we obtain a systematic topological expansion, with more and…
U(N) tools for Loop Quantum Gravity: The Return of the Spinor
Enrique F. Borja, Laurent Freidel, Iñaki Garay +1
We explore the classical setting for the U(N) framework for SU(2) intertwiners for loop quantum gravity (LQG) and describe the corresponding phase space in terms of spinors with ap…
Discreteness and the transmission of light from distant sources
Fay Dowker, Joe Henson, Rafael Sorkin
We model the classical transmission of a massless scalar field from a source to a detector on a background causal set. The predictions do not differ significantly from those of the…
Black holes in an ultraviolet complete quantum gravity
Leonardo Modesto, John W. Moffat, Piero Nicolini
In this Letter we derive the gravity field equations by varying the action for an ultraviolet complete quantum gravity. Then we consider the case of a static source term and we det…
