Magnetically charged black holes and their stability.
We study magnetically charged black holes in the Einstein-Yang-Mills-Higgs theory in the limit of infinitely strong coupling of the Higgs field. Using mixed analytical and numerical methods we give a complete description of static spherically symmetric black hole solutins, both abelian and nonabelian. In particular we find a new class of extremal nonabelian solutions. We show that all nonabelia...
متن کاملQuantum-mechanical scattering of charged black holes.
We describe the quantum mechanical scattering of slowly moving maximally charged black holes. Our technique is to develop a canonical quantization procedure on the parameter space of possible static classical solutions. With this, we compute the capture cross sections for the scattering of two black holes. Finally, we discuss how quantization on this parameter space relates to quantization of t...
متن کاملQuantum Entropy of Charged Rotating Black Holes
For more than two decades physicists have come to appreciate black holes as thermodynamic systems characterized by only a few macroscopic parameters such as mass (m), charge (q) and angular momentum (Ω). The generic representative of such a hole in general relativity is the Kerr-Newman metric . The thermodynamic analogy suggests that there is an entropy associated with this hole that is proport...
متن کاملThermal stability of radiant black holes
Beginning with a brief sketch of the derivation of Hawking’s theorem of horizon area increase, based on the Raychaudhuri equation, we go on to discuss the issue as to whether generic black holes, undergoing Hawking radiation, can ever remain in stable thermal equilibrium with that radiation. We derive a universal criterion for such a stability, which relates the black hole mass and microcanonic...
متن کاملCharged Black Holes
We study the geodesic motions of a test particle around 2 + 1 dimensional charged black holes. We obtain a class of exact geodesic motions for the massless test particle when the ratio of its energy and angular momentum is given by square root of cosmological constant. The other geodesic motions for both massless and massive test particles are analyzed by use of numerical method. PACS number(s)...
