Geodesic motions near an improved Schwarzschild black hole

نویسندگان

چکیده

In this paper, we studied the geodesics of timelike and null like particles near an improved Schwarzschild black hole. The lapse function has been plotted was found that only one horizon is possible. equation motion effective potential test particle have calculated. This importance in studying radial free fall stability orbits (trajectories). energy angular momentum also calculated to analysis cicrular circular orbits. Moreover, Innermost stable orbit radius determined. To get a deeper insight nature these trajectories, with help dynamical systems approach. us determine as well fixed point phase space trajectories.

Entropy of Scalar Field near a Schwarzschild Black Hole Horizon

In this paper we compute the correction to the entropy of Schwarzschild black hole due to the vacuum polarization effect of massive scalar field. The Schwarzschild black hole is supposed to be confined in spherical shell. The scalar field obeying mixed boundary condition on the spherical shell.

Entropy of Schwarzschild black hole and string-black hole correspondence

The string-black hole correspondence is considered in the context of the correspondence principle proposed recently by Horowitz and Polchinski [7]. We demonstrate that the entropy of string states and the entropy of a Schwarzschild black hole can be matched including the subleading terms which depend on mass logarithmically. We argue the necessity to include the string interaction (with couplin...

Area spectrum of the Schwarzschild black hole.

We consider a Hamiltonian theory of spherically symmetric vacuum Einstein gravity under Kruskal-like boundary conditions in variables associated with the Einstein-Rosen wormhole throat. The configuration variable in the reduced classical theory is the radius of the throat, in a foliation that is frozen at the left hand side infinity but asymptotically Minkowski at the right hand side infinity, ...

Hamiltonian thermodynamics of the Schwarzschild black hole.

Kuchař has recently given a detailed analysis of the classical and quantum geometrodynamics of the Kruskal extension of the Schwarzschild black hole. In this paper we adapt Kuchař’s analysis to the exterior region of a Schwarzschild black hole with a timelike boundary. The reduced Lorentzian Hamiltonian is shown to contain two independent terms, one from the timelike boundary and the other from...
