Supermassive boson stars: prospects for observational detection
Diego F. Torres, S. Capozziello, G. Lambiase
In a recent work (Torres, Capozziello and Lambiase, Physical Review D62, 104012 (2000)), it was shown that a supermassive boson star could provide an alternative model for the gala…
Radiation from a uniformly accelerated charge in the outskirts of a wormhole throat
Luis A. Anchordoqui, S. Capozziello, G. Lambiase +1
Using traversable wormholes as theoretical background, we revisit a deep question of general relativity: Does a uniformly accelerated charged particle radiate? We particularize to…
Thin shell quantization in Weyl spacetime
S. Capozziello, A. Feoli, G. Lambiase +1
We study the problem of quantization of thin shells in a Weyl-Dirac theory by deriving a Wheeler-DeWitt equation from the dynamics. Solutions are found which have interpretations i…
Cerenkov radiation and scalar stars
S. Capozziello, G. Lambiase, Diego F. Torres
We explore the possibility that a charged particle moving in the gravitational field generated by a scalar star could radiate energy via a recently proposed gravitational Čerenkov…
Massive Scalar Particles in a Modified Schwarzschild Geometry
S. Capozziello, A. Feoli, G. Lambiase +2
Massive, spinless bosons have vanishing probability of reaching the sphere r=2M from the region r>2M when the original Schwarzschild metric is modified by maximal acceleration corr…
Inertial Effects on Berry's Phase of Neutrino Oscillations
S. Capozziello, G. Lambiase
The Berry phase of mixed states, as neutrino oscillations, is calculated in a accelerating and rotating reference frame. It turns out to be depending on the vacuum mixing angle, th…
