چکیده
In this work we study thermodynamics of 2+1-dimensional static black holes with a nonlinear electric field. Besides employing the standard thermodynamic approach, investigate hole by studying its geometry. We compute Weinhold and Ruppeiner metrics compare geometry description on thermodynamics. further consider cosmological constant as an additional extensive variable. equilibrium three dimensional space, efficiency heat engine show that it is possible to be built hole.

Nonlinear Electrodynamics and Black Holes
It is addressed the issue of black holes with nonlinear electromagnetic field, focussing mainly in the Born-Infeld case. The main features of these systems are described, for instance, geodesics, energy conditions, thermodynamics. Also it is revised some black hole solutions of alternative nonlinear electrodynamics and its inconveniences.
متن کاملEnergy-momentum/Cotton tensor duality for AdS4 black holes
We consider the theory of gravitational quasi-normal modes for general linear perturbations of AdS4 black holes. Special emphasis is placed on the effective Schrödinger problems for axial and polar perturbations that realize supersymmetric partner potential barriers on the half-line. Using the holographic renormalization method, we compute the energy-momentum tensor for perturbations satisfying...
متن کامل2+1-dimensional black holes with momentum and angular momentum
Exact solutions of Einstein’s equations in 2+1-dimensional anti-de Sitter space containing any number of black holes are described. In addition to the black holes these spacetimes can possess “internal” structure. Accordingly the generic spacetime of this type depends on a large number of parameters. Half of these can be taken as mass parameters, and the rest as the conjugate (angular) momenta....
متن کاملRegular magnetic black holes and monopoles from nonlinear electrodynamics
It is shown that general relativity coupled to nonlinear electrodynamics (NED) with the Lagrangian L(F ) , F = FμνF μν having a correct weak field limit, leads to nontrivial spherically symmetric solutions with a globally regular metric if and only if the electric charge is zero and L(F ) tends to a finite limit as F →∞ . Properties and examples of such solutions, which include magnetic black h...
متن کاملA ug 2 00 7 Scalar - tensor black holes coupled to Euler - Heisenberg nonlinear electrodynamics
The no-scalar-hair conjecture rules out the existence of asymptotically flat black holes with a scalar dressing for a large class of theories. No-scalar-hair theorems have been proved for the cases of neutral black holes and for charged black holes in the Maxwell electrodynamics. These theorems, however, do not apply in the case of non-linear electrodynamics. In the present work numerical solut...
