Massimo Blasone, Antonio Capolupo, Enrico Celeghini, Giuseppe, Vitiello
TL;DR
This paper investigates non-cyclic phases in neutrino oscillations within quantum field theory, revealing their connection to the vacuum structure and how they relate to quantum mechanical geometric phases.
Contribution
It introduces the concept of non-cyclic phases in neutrino oscillations in quantum field theory and links these phases to the non-perturbative vacuum structure.
Findings
Non-cyclic phases exist for neutrino oscillations in quantum field theory.
These phases encode information about the vacuum condensate.
Subtracting the condensate recovers the quantum mechanics geometric phase.
Abstract
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 structure associated with the field mixing. By subtracting the condensate contribution of the flavor vacuum, the previously studied quantum mechanics geometric phase is recovered.
