New Type of Regular Black Holes and Particlelike Solutions from Nonlinear Electrodynamics
نویسندگان
چکیده
We show that the Bronnikov theorem on the nonexistence of regular electrically charged black holes can be circumvented. In the frame of nonlinear electrodynamics, we present the exact regular black hole solutions of a hybrid type. They are electrically charged, but contain a ‘dual’ core confining a polarization of magnetic charges. The considered example is based on a modification of the AyónBeato & Garćıa solution. It represents a very specific realization of the idea on confinement based on dual electrodynamics and dual superconductivity.

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 کاملEinstein-Skyrme Solitons and Black Holes
In the SU(3) Einstein-Skyrme system static spherically symmetric particlelike solutions and black holes exist for both the SU(2) and the SO(3) embedding. The SO(3) embedding leads to new particle-like solutions and black holes, sharing many features with the SU(2) solutions. In particular, there are always two branches of solutions, forming a cusp at a critical coupling constant. The regular SO...
متن کامل2 8 A pr 2 00 7 Scalar - tensor black holes coupled to Born - Infeld nonlinear electrodynamics
The non-existence of asymptotically flat, neutral black holes and asymptotically flat, charged black holes in the Maxwell electrodynamics, with non-trivial scalar field has been proved for a large class of scalar-tensor theories. The noscalar-hair theorems, however, do not apply in the case of non-linear electrodynamics. In the present work numerical solutions describing charged black holes cou...
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...
