Propagation in a thermal graviton background
Daniel Arteaga, Renaud Parentani, Enric Verdaguer
It is well known that radiative corrections evaluated in nontrivial backgrounds lead to effective dispersion relations which are not Lorentz invariant. Since gravitational interact…
On the Gravitational Back Reaction to Hawking Radiation
S. Massar, R. Parentani
We show that a surface term should be added to the Einstein-Hilbert action in order to properly describe quantum transitions occurring around a black hole. The introduction of this…
The notions of time and evolution in quantum cosmology
R. Parentani
We re-examine the notions of time and evolution in the light of the mathematical properties of the solutions of the Wheeler-DeWitt equation which are revealed by an extended adiaba…
The validity of the Background Field Approximation
R. Parentani
In the absence of a tractable theory of quantum gravity, quantum matter field effects have been so far computed by treating gravity at the Background Field Approximation. The princ…
