Incompressible fluid inside an astrophysical black hole?
Fabrizio Canfora
It is argued that under natural hypothesis the Fermions inside a black hole formed after the collapse of a neutron star could form a non compressible fluid (well before reaching th…
Some exact solutions with torsion in 5-D Einstein-Gauss-Bonnet gravity
F. Canfora, A. Giacomini, S. Willison
Exact solutions with torsion in Einstein-Gauss-Bonnet gravity are derived. These solutions have a cross product structure of two constant curvature manifolds. The equations of moti…
A note on Tachyon dynamics
F. Canfora
A suitable splitting of tachyon field equation is able to disclose non trivial properties of Born-Infeld (some known, some unexpected) and Polyakov actions; the tachyon equation al…
The Holographic Principle and the Early Universe
F. Canfora, G. Vilasi
A scenario is proposed in which the matter-antimatter asymmetry behaves like a seed for the inflationary phase of the universe. The mechanism which makes this scenario plausible is…
Does the Holographic Principle determine the Gravitational Interaction?
F. Canfora, G. Vilasi
It is likely that the holographic principle will be a consequence of the would be theory of quantum gravity. Thus, it is interesting to try to go in the opposite direction: can the…
Hamilton-Jacobi equation and the breaking of the WKB approximation
Fabrizio Canfora
A simple method to deal with four dimensional Hamilton-Jacobi equation for null hypersurfaces is introduced. This method allows to find simple geometrical conditions which give ris…
