The Kerr-Newman-Gödel Black Hole
By applying a set of Hassan-Sen transformations and string dualities to the Kerr-Gödel solution of minimal D = 5 supergravity we derive a four parameter family of five dimensional solutions in type II string theory. They describe rotating, charged black holes in a rotating background. For zero background rotation, the solution is D = 5 Kerr-Newman; for zero charge it is Kerr-Gödel. In a particu...
متن کاملDecay Rates and Probability Estimates for Massive Dirac Particles in the Kerr–Newman Black Hole Geometry
The Cauchy problem is considered for the massive Dirac equation in the non-extreme Kerr–Newman geometry, for smooth initial data with compact support outside the event horizon and bounded angular momentum. We prove that the Dirac wave function decays in L∞loc at least at the rate t−5/6. For generic initial data, this rate of decay is sharp. We derive a formula for the probabilityp that the Dira...
متن کاملGeometry of Black Hole Thermodynamics
The Hessian of the entropy function can be thought of as a metric tensor on the state space. In the context of thermodynamical fluctuation theory Ruppeiner has argued that the Riemannian geometry of this metric gives insight into the underlying statistical mechanical system; the claim is supported by numerous examples. We study this geometry for some families of black holes. It is flat for the ...
متن کاملThe Proton as A Kerr-Newman Black Hole
The general equation governing the mass, spin and angular momentum of a KerrNewman black hole applies equally well to a proton when the gravitational coupling constant predicted by a discrete fractal paradigm is used in the equation, along with the standard mass, spin and angular momentum of the proton. c © Electronic Journal of Theoretical Physics.

متن کاملHawking temperature of Kerr-Newman-AdS black hole from tunneling
Using the null-geodesic tunneling method of Parikh and Wilczek, we derive the Hawking temperature of a general four-dimensional rotating black hole. In order to eliminate the motion of φ degree of freedom of a tunneling particle, we have chosen a reference system that is co-rotating with the black hole horizon. Then we give the explicit result for the Hawking temperature of the Kerr-Newman-AdS ...
