Quantum State of Black-Holes Out of Equilibrium
Yotam Sherf
We study the properties of black-holes (BHs) that are out of equilibrium about the Hartle-Hawking (HH) vacuum state. We show how gravitational perturbations excite the vacuum state…

Emission Channels from Perturbed Quantum Black Holes
Ram Brustein, Yotam Sherf
We calculate the emission of gravitational waves, gravitons, photons and neutrinos from a perturbed Schwarzschild blackhole (BH). The perturbation can be due to either classical or…

Hyperbolicity Constraints in Extended Gravity Theories
Yotam Sherf
We study the characteristic structure of the Einstein-Hilbert (EH) action when modifications of the form of , and are included. We show th…
