Horizon surface gravity as 2d geodesic expansion
Ted Jacobson, Renaud Parentani
The surface gravity of any Killing horizon, in any spacetime dimension, can be interpreted as a local, two-dimensional expansion rate seen by freely falling observers when they cro…
A Primer for Black Hole Quantum Physics
Robert Brout, Serge Massar, Renaud Parentani +1
The mechanisms which give rise to Hawking radiation are revealed by analyzing in detail pair production in the presence of horizons. In preparation for the black hole problem, thre…
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…
