Features of Fermion Dynamics Revealed by SU2 Symmetry

We deal here with the notion of statistical order and apply it to a system interacting fermions endowed an SU2 × symmetry. The discussion takes place in thermal quantum scenario. Two distinct fermion–fermion interactions are at play. One them is well-known spin–flip interaction. other pairing interaction responsible for nuclear superconductivity. used novel quantifiers that yield insights regarding changes produced when values pertinent coupling constants vary. In particular, we show judicious manipulation energy cost associated variations fermion number key understanding important details dynamics.
