New exact solutions in multi-scalar field cosmology
Jorge G. Russo
We use the method of the superpotential to derive exact solutions describing inflationary cosmologies in multi-field models. An example that describes a solution that interpolates…
Displaced orbits and electric-magnetic black hole binaries
Jorge G. Russo
In presence of magnetic fields, the orbits of charged particles can be displaced from the equatorial plane. We study circular orbits of electrically charged massive objects around…
Exact gravitational plane waves and two-dimensional gravity
Jorge G. Russo
We discuss dynamical aspects of gravitational plane waves in Einstein theory with massless scalar fields. The general analytic solution describes colliding gravitational waves with…
Energy-momentum tensor for scalar fields coupled to the dilaton in two dimensions
Fernando C. Lombardo, Francisco D. Mazzitelli, Jorge G. Russo
We clarify some issues related to the evaluation of the mean value of the energy-momentum tensor for quantum scalar fields coupled to the dilaton field in two-dimensional gravity.…
