On Hawking Radiation as Tunneling with Logarithmic Corrections
A. J. M. Medved, Elias C. Vagenas
There has been recent speculation that the tunneling paradigm for Hawking radiation could -- after quantum-gravitational effects have suitably been incorporated -- provide a means…
Hawking Radiation as Tunneling through the Quantum Horizon
Michele Arzano, A. J. M. Medved, Elias C. Vagenas
Planck-scale corrections to the black-hole radiation spectrum in the Parikh-Wilczek tunneling framework are calculated. The corrective terms arise from modifications in the express…
On Hawking Radiation as Tunneling with Back-Reaction
A. J. M. Medved, Elias C. Vagenas
Recently, Angheben et.al. [hep-th/0503081] have presented a refined method for calculating the (tree-level) black hole temperature by way of the tunneling paradigm. In the current…
Cosmological significance of one-loop effective gravity
D. Espriu, T. Multamaki, E. C. Vagenas
We study the one-loop effective action for gravity in a cosmological setup to determine possible cosmological effects of quantum corrections to Einstein theory. By considering the…
