Second-order effective energy-momentum tensor of gravitational scalar perturbations with perfect fluid
Inyong Cho, Jinn-Ouk Gong, Seung Hun Oh
We investigate the second-order gravitational scalar perturbations for a barotropic fluid. We derive the effective energy-momentum tensor described by the quadratic terms of the gr…

Gravitating superconducting solitons in the (3+1)-dimensional Einstein gauged non-linear sigma-model
Fabrizio Canfora, Alex Giacomini, Marcela Lagos +2
In this paper, we construct the first analytic examples of (3+1)-dimensional self-gravitating regular cosmic tube solutions which are superconducting, free of curvature singulariti…
