Spin, torsion and violation of null energy condition in traversable wormholes
Emmanuele Battista, Elisabetta Di Grezia, Mattia Manfredonia +1
The static spherically symmetric traversable wormholes are analysed in the Einstein- Cartan theory of gravitation. In particular, we computed the torsion tensor for matter fields w…
Black hole evaporation in a spherically symmetric non-commutative space-time
Elisabetta Di Grezia, Giampiero Esposito, Gennaro Miele
Recent work in the literature has studied the quantum-mechanical decay of a Schwarzschild-like black hole, formed by gravitational collapse, into almost-flat space-time and weak ra…
Minimal coupling of the Kalb-Ramond field to a scalar field
E. Di Grezia, S. Esposito
We study the direct interaction of an antisymmetric Kalb-Ramond field with a scalar particle derived from a gauge principle. The method outlined in this paper to define a covariant…
