Hyperbolic space in the Newtonian limit: the cosmological constant
J. C. Castro-Palacio, P. Fernandez de Cordoba, R. Gallego Torrome +1
The cosmological constant and the Boltzmann entropy of a Newtonian Universe filled with a perfect fluid are computed, under the assumption that spatial sections are copies of 3-dim…
Quantum illumination with multiple entangled photons
Ricardo Gallego Torromé, Nadya Ben Bekhti-Winkel, Peter Knott
In this work, a theoretical generalization of Lloyd's quantum illumination to signal beams described by two entangled photon states is developed. It is shown that the new protocol…
On -jet field approximations to geodesic deviation equations
Ricardo Gallego Torromé, Jonathan Gratus
Let be a smooth manifold and a semi-spray defined on a sub-bundle of the tangent bundle . In this work it is proved that the only non-trivial $k…
On a rigidity condition for Berwald Spaces
Ricardo Gallego Torrome, Fernando Etayo
We show that which that for a Berwald structure, any Riemannian structure that is preserved by the Berwald connection leaves the indicatrix invariant under horizontal parallel tran…
