Demonstration of Communication using Neutrinos
D. D. Stancil, P. Adamson, M. Alania +109
Beams of neutrinos have been proposed as a vehicle for communications under unusual circumstances, such as direct point-to-point global communication, communication with submarines…
On the Meaning of the Principle of General Covariance
Alberto Chamorro
We present a definite formulation of the Principle of General Covariance (GCP) as a Principle of General Relativity with physical content and thus susceptible of verification or co…
A Tolman-Bondi-Lemaitre Cell-Model for the Universe and Gravitational Collapse
A. Chamorro, S. S. Deshingkar, I. H. Dwivedi +1
A piecewise Tolman-Bondi-Lemaitre (TBL) cell-model for the universe incorporating local collapsing and expanding inhomogeneities is presented here. The cell-model is made up of TBL…
Gravitational Collapse and Cosmological Constant
S. S. Deshingkar, S. Jhingan, A. Chamorro +1
We consider here the effects of a non-vanishing cosmological term on the final fate of a spherical inhomogeneous collapsing dust cloud. It is shown that depending on the nature of…
Assisted inflation in Friedmann-Robertson-Walker and Bianchi spacetimes
J. M. Aguirregabiria, A. Chamorro, L. P. Chimento +1
We use exact general solutions for the spatially flat FRW and the anisotropic Bianchi I cosmologies to show that generically uncoupled scalar fields cooperate to make inflation mor…
Energy of a spherically symmetric charged dilaton black hole
A. Chamorro, K. S. Virbhadra
The energy associated with a static and spherically symmetric charged dilaton black hole is obtained for arbitrary value of the coupling parameter (which regulates the strength of…
