Black Hole Horizon Fluctuations
A. Casher, F. Englert, N. Itzhaki +2
It is generally admitted that gravitational interactions become large at an invariant distance of order from the black hole horizon. We show that due to the ``atmosphere'' of h…

Applications of the Complex Geometric "Phase" for Meta-stable Systems
S. Massar
Garrison and Wright showed that upon undergoing cyclic quantum evolution a meta-stable state acquires both a geometric phase and a geometric decay probability. This is described by…

The Schwinger Mechanism, the Unruh Effect and the Production of Accelerated Black Holes
R. Parentani, S. Massar
We compute the corrections to the transition amplitudes of an accelerated Unruh ``box'' that arise when the accelerated box is replaced by a ``two level ion'' immersed in a constan…
