Born-Infeld generalization of the Reissner-Nordström black hole
نویسنده
چکیده
In this work we study the trajectories of test particles in a geometry that is the nonlinear electromagnetic generalization of the ReissnerNordström solution. The studied spacetime is a Einstein-Born-Infeld solution, nonsingular outside a regular event horizon and characterized by three parameters: mass M , charge Q and the Born-Infeld parameter b related to the magnitude of the electric field at the origin. Asymptotically it is a Reissner-Nordström solution.

Area Spectrum of Extremal Reissner-Nordström Black Holes from Quasi-normal Modes
Using the quasi-normal modes frequency of extremal Reissner-Nordström black holes, we obtain area spectrum for these type of black holes. We show that the area and entropy black hole horizon are equally spaced. Our results for the spacing of the area spectrum differ from that of schwarzschild black holes. ∗E-mail: [email protected]
متن کاملDispersion Relations for Cold Plasmas around Reissner-Nordström Black Holes
We investigate the general relativistic magnetohydrodynamic (GRMHD) equations for cold plasma around the Reissner-Nordström black hole. Applying 3+1 spacetime split we linearize the perturbed equations for non-magnetized/magnetized plasma in both rotating and non-rotating background. By Fourier analyze we then derive dispersion relations and investigate the existence of waves with positive angu...
متن کاملNon-Existence of Time-Periodic Solutions of the Dirac Equation in a Reissner-Nordström Black Hole Background
It is shown analytically that the Dirac equation has no normalizable, time-periodic solutions in a Reissner-Nordström black hole background; in particular, there are no static solutions of the Dirac equation in such a background metric. The physical interpretation is that Dirac particles can either disappear into the black hole or escape to infinity, but they cannot stay on a periodic orbit aro...
متن کاملLogarithmic correction to the Cardy-Verlinde formula in Topological Reissner-Nordström de Sitter Space
In this paper we compute leading order correction due to small statistical fluctuations around equilibrium, to the Cardy-Verlinde entropy formula (which is supposed to be an entropy formula of conformal field theory in any dimension) of a Topological Reissner-Nordstrom black hole in de Sitter space. ∗E-mail: [email protected]
متن کاملEnergy distribution in the dyadosphere of a Reissner-Nordström black hole in Møller’s prescription
The energy and momentum distributions in the dyadosphere of a Reissner-Nordström black hole are evaluated. The Møller’s energy-momentum complex is employed for this computation. The spacetime under study is modified due to the effects of vacuum fluctuations in the dyadosphere. Therefore, the corrected Reissner-Nordström black hole metric takes into account the first contribution of the weak fie...
