Fw. Hehl et J. Socorro, GAUGE-THEORY OF GRAVITY - ELECTRICALLY CHARGED SOLUTIONS WITHIN THE METRIC-AFFINE FRAMEWORK, ACT PHY P B, 29(4), 1998, pp. 1113-1120
We find a class of electrically charged exact solutions for a toy mode
l of metric-affine gravity. Their metric is of the Plebanski-Demianski
type and their nonmetricity and torsion are represented by a triplet
of covectors with dilation, shear, and spill charges.
