Magnetic String with a Nonlinear U(1)‎ Source

الملخص EN

Considering the Einstein gravity in the presence of Born-Infeld type electromagnetic fields, we introduce a class of 4-dimensional static horizonless solutions which produce longitudinal magnetic fields.

Although these solutions do not have any curvature singularity and horizon, there exists a conic singularity.

We investigate the effects of nonlinear electromagnetic fields on the properties of the solutions and find that the asymptotic behavior of the solutions is adS.

Next, we generalize the static metric to the case of rotating solutions and find that the value of the electric charge depends on the rotation parameter.

Furthermore, conserved quantities will be calculated through the use of the counterterm method.

Finally, we extend four-dimensional magnetic solutions to higher dimensional solutions.

We present higher dimensional rotating magnetic branes with maximum rotation parameters and obtain their conserved quantities.
