On the canonical quantization of the electromagnetic field and the emergence of gauge invariance
M. Blasone, E. Celeghini, P. Jizba +2
In the framework of the canonical quantization of the electromagnetic field, we impose as primary condition on the dynamics the positive definiteness of the energy spectrum. This i…
Geometric phase of neutrinos: differences between Dirac and Majorana neutrinos
A. Capolupo, S. M. Giampaolo, B. C. Hiesmayr +1
We analize the non-cyclic geometric phase for neutrinos. We find that the geometric phase and the total phase associated to the mixing phenomenon provide a tool to distinguish betw…
Geometric phase and gauge theory structure in quantum computing
A. Bruno, A. Capolupo, S. Kak +2
We discuss the presence of a geometrical phase in the evolution of a qubit state and its gauge structure. The time evolution operator is found to be the free energy operator, rathe…
Gauge theory and two level systems
A. Bruno, A. Capolupo, S. Kak +2
We consider the time evolution of a two level system (a two level atom or a qubit) and show that it is characterized by a local (in time) gauge invariant evolution equation. The co…
Cosmological effects of neutrino mixing
M. Blasone, A. Capolupo, S. Capozziello +1
We report on the recent result that a contribution to the dark energy can be achieved by the vacuum condensate induced by neutrino mixing phenomenon.
Domain formation in noninstantaneous symmetry breaking phase transitions
E. Alfinito, G. Vitiello
In the framework of the Ginzburg-Landau harmonic potential approximation, we present a possible modeling of the time-dependence of the frequency of the order parameter mode suitabl…
