Magnetic point sources in three-dimensional Brans-Dicke gravity theories
Magnetic point sources in three-dimensional Brans-Dicke gravity theories
We obtain geodesically complete spacetimes generated by static and rotating magnetic point sources in an Einstein-Maxwell-dilaton theory of the Brans-Dicke type in three dimensions (3D). The theory is specified by three fields, the dilaton φ, the graviton gμν and the electromagnetic field Fμν, and two parameters, the cosmological constant Λ<0 and the Brans-Dicke parameter ω. For ω=±∞, our solution reduces to the magnetic counterpart of the BTZ solution, while the ω=0 case is equivalent to 4D general relativity with one Killing vector. The source for the magnetic field can be interpreted as composed by a system of two symmetric and superposed electric charges. One of the electric charges is at rest and the other is spinning.

Abstract
We obtain geodesically complete spacetimes generated by static and rotating magnetic point sources in an Einstein-Maxwell-dilaton theory of the Brans-Dicke type in three dimensions (3D). The theory is specified by three fields, the dilaton φ, the graviton gμν and the electromagnetic field Fμν, and two parameters, the cosmological constant Λ<0 and the Brans-Dicke parameter ω. For ω=±∞, our solution reduces to the magnetic counterpart of the BTZ solution, while the ω=0 case is equivalent to 4D general relativity with one Killing vector. The source for the magnetic field can be interpreted as composed by a system of two symmetric and superposed electric charges. One of the electric charges is at rest and the other is spinning.
