After reviewing the formalism for describing flavor mixing, both in Quantum Mechanics and Quantum Field Theory, some consequences along three different directions are studied. First, it is proposed that flavor mixing can ...

In this dissertation we discuss several aspects of a two level system (qubit) in the context of quantum mechanics and quantum field theory. The presence of geometrical phases in the evolution of a qubit state is shown. We ...

The relentless quest for unraveling the true mechanisms that govern the Nature we observe and are part of have led physicists to rely on the adoption of fundamental principles. These assumptions have acted as a guiding ...
