Propagation of vacuum polarized photons in topological black hole spacetimes

The one-loop effective action for QED in curved spacetime contains equivalence principle violating interactions between the electromagnetic field and the spacetime curvature. These interactions lead to the dependence of photon velocity on the motion and polarization directions. In this paper we investigate the gravitational analogue to the electromagnetic birefringence phenomenon in the static ...

Numerical Study of 3d Rotating Black Hole Spacetimes By

We present new developments in 3D numerical relativity that bring the field for the first time close to providing useful astrophysical information about the orbital merger of binary black holes relevant for interferometric gravitational wave detectors, coming on line by the end of 2001. Our study begins with two different families of black hole initial data, a new single distorted spinning blac...

Black Hole Solutions and Pair Creation of Black Holes in Three, Four and Higher Dimensional Spacetimes

Black holes, first found as solutions of Einstein’s General Relativity, are important in astrophysics, since they result from the gravitational collapse of a massive star or a cluster of stars, and in physics since they reveal properties of the fundamental physics, such as thermodynamic and quantum properties of gravitation. In order to better understand the black hole physics we need exact sol...
