Oscillating dark energy: a possible solution to the problem of eternal acceleration
C. Rubano, P. Scudellaro, E. Piedipalumbo +1
We present a dark energy model with a double exponential potential for a minimally coupled scalar field, which allows general exact integration of the cosmological equations. The s…
Exponential Potentials for Tracker Fields
C. Rubano, P. Scudellaro, E. Piedipalumbo +2
We show that a general, exact cosmological solution, where dynamics of scalar field is assigned by an exponential potential, fulfils all the issues of dark energy approach, both fr…
Curvature quintessence matched with observational data
S. Capozziello, V. F. Cardone, S. Carloni +1
Quintessence issues can be achieved by taking into account higher order curvature invariants into the effective action of gravitational field. Such an approach is naturally related…
Gravitomagnetic corrections to the lensing deflection angle for spiral galaxy models
S. Capozziello, V. F. Cardone, V. Re +1
We investigate the effects of the gravitomagnetic corrections to the usual gravitational lens quantities for a specific lensing mass distribution modelled after spiral galaxies. An…
Neutrino condensates at center of galaxies as background for the MSW mechanism
S. Capozziello, G. Iovane, G. Lambiase
The possibility is explored that neutrino condensates, possible candidates for the explanation of very massive objects in galactic centers, could act as background for the Mikheyev…
Quintessence without scalar fields
S. Capozziello, S. Carloni, A. Troisi
The issues of quintessence and cosmic acceleration can be discussed in the framework of theories which do not include necessarily scalar fields. It is possible to define pressure a…
