Effective Observer-Split Source Terms in Rotating Frames and Gravitomagnetic Backgrounds in Extended Aharonov-Bohm Electrodynamics
A. Iadicicco, G. Modanese, L. Verolino
We examine whether the observer split of a covariantly conserved electric current in a rotating finite system can provide a physically constrained effective source for the scalar s…
Covariant formulation of Aharonov-Bohm electrodynamics and its application to coherent tunnelling
G. Modanese
The extended electrodynamic theory introduced by Aharonov and Bohm (after an earlier attempt by Ohmura) and recently developed by Van Vlaenderen and Waser, Hively and Giakos, can b…
Gravitational radiation of a vibrating physical string as a model for the gravitational emission of an astrophysical plasma
R. A. Lewis, G. Modanese
The vibrating string is a source of gravitational waves which requires novel computational techniques, based on the explicit construction of a conserved and renormalized (in a clas…
Tunneling of a Massless Field through a 3D Gaussian Barrier
G. Modanese
We propose a method for the approximate computation of the Green function of a scalar massless field Phi subjected to potential barriers of given size and shape in spacetime. This…
Possible quantum gravity effects in a charged Bose condensate under variable e.m. field
G. Modanese, J. Schnurer
In the weak field approximation to quantum gravity, a "local" positive cosmological term mu^2(x) corresponds to a local negative squared mass term in the Lagrangian and may thus in…
General properties of the decay amplitudes for massless particles
G. Fiore, G. Modanese
We derive the kinematical constraints which characterize the decay of any massless particle in flat spacetime. We show that in perturbation theory the decay probabilities of photon…
General Estimate for the Graviton Lifetime
G. Modanese
By means of general kinematical arguments, the lifetime of a graviton of energy for decay into gravitons is found to have the form $τ^{-1} = \frac{1}{EG} \sum_{j=1,2,...} c…
The radial gauge propagators in quantum gravity
P. Menotti, G. Modanese, D. Seminara
We give a general procedure for extracting the propagators in gauge theories in presence of a sharp gauge fixing and we apply it to derive the propagators in quantum gravity in the…
