Large N wormhole approach to spacetime foam
Remo Garattini
A simple model of spacetime foam, made by wormholes in a semiclassical approximation, is taken under examination. We show that the qualitative behaviour of the fluctuation of t…
The statistics of the gravitational field arising from an inhomogenous system of particles
A. Del Popolo, M. Gambera, x
In this paper we extend Chandrasekhar and von Neumann's analysis of the statistics of the gravitational field to systems in which particles (e.g. stars, galaxies) are not homogeneo…
On Superluminal motions in photon and particle tunnelings
J. Jakiel, V. S. Olkhovsky, Erasmo Recami
It is shown that the Hartman-Fletcher effect is valid for all the known expressions of the mean tunnelling time, in various nonrelativistic approaches, for the case of finite width…
The effect of non-radial motions on the X-ray temperature distribution function and the two-point correlation function of clusters
A. Del Popolo, M. Gambera
We show how non-radial motions, originating in the outskirts of clusters of galaxies, may reduce the discrepancy between the Cold Dark Matter (CDM) predicted X-ray temperature dist…
Probing foamy spacetime with Variational Methods
Remo Garattini
A one-loop correction of the quasilocal energy in the Schwarzschild background, with flat space as a reference metric, is performed by means of a variational procedure in the Hamil…
Radiation Induced Fermion Resonance
S. Esposito, M. W. Evans, E. Recami
The Dirac equation is solved for two novel terms which describe the interaction energy between the half integral spin of a fermion and the classical, circularly polarized, electrom…
