Non-cyclic phases for neutrino oscillations in quantum field theory
Massimo Blasone, Antonio Capolupo, Enrico Celeghini +1
We show the presence of non-cyclic phases for oscillating neutrinos in the context of quantum field theory. Such phases carry information about the non-perturbative vacuum structur…

Particle mixing as possible explanation of the dark energy conundrum
Antonio Capolupo, Giuseppe Vitiello
The vacuum condensate due to neutrino and quark mixing behaves as a perfect fluid and, at the present epoch, as a cosmological constant. The very small breaking of the Lorentz inva…

Dark energy and particle mixing
A. Capolupo, S. Capozziello, G. Vitiello
We show that the vacuum condensate due to particle mixing is responsible of a dynamically evolving dark energy. In particular, we show that values of the adiabatic index close to -…
