Generating Gowdy cosmological models
A. Sanchez, A. Macias, H. Quevedo
Using the analogy with stationary axisymmetric solutions, we present a method to generate new analytic cosmological solutions of Einstein's equation belonging to the class of …

Plebański-Demiański-like solutions in metric-affine gravity
A. Garcia, F. W. Hehl, C. Laemmerzahl +2
We consider a (non--Riemannian) metric--affine gravity theory, in particular its nonmetricity--torsion sector ``isomorphic'' to the Einstein--Maxwell theory. We map certain Einstei…

On the structure of the energy-momentum and the spin currents in Dirac's electron theory
F. W. Hehl, A. Macías, E. W. Mielke +1
We consider a classical Dirac field in flat Minkowski spacetime. We perform a Gordon decomposition of its canonical energy-momentum and spin currents, respectively. Thereby we find…
