The discussion takes place in a thermal quantum statistical scenario. Two distinct fermion\u2013fermion interactions are at play. One of them is a well-known spin\u2013flip interaction. The other is the pairing interaction responsible for nuclear superconductivity. We used novel statistical quantifiers that yield insights regarding changes in the statistical order produced when the values of the pertinent coupling constants vary. In particular, we show that judicious manipulation of the energy cost associated with statistical order variations with the fermion number is the key to understanding important details of the associated dynamics.<\/jats:p>","DOI":"10.3390\/sym14102179","type":"journal-article","created":{"date-parts":[[2022,10,18]],"date-time":"2022-10-18T00:31:01Z","timestamp":1666053061000},"page":"2179","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Features of Fermion Dynamics Revealed by SU2 Symmetry"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5934-2783","authenticated-orcid":false,"given":"Angelo","family":"Plastino","sequence":"first","affiliation":[{"name":"Instituto de F\u00edsica La Plata\u2014CCT-CONICET, Universidad Nacional de La Plata, C.C. 727, La Plata 1900, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gustavo Luis","family":"Ferri","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Universidad Nacional de La Pampa, Santa Rosa 6300, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angel Ricardo","family":"Plastino","sequence":"additional","affiliation":[{"name":"CeBio-Departamento de Ciencias B\u00e1sicas, Universidad Nacional del Noroeste de la Prov. de Buenos Aires (UNNOBA), CONICET, Junin 6000, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"828","DOI":"10.1016\/j.physa.2018.05.003","article-title":"Complexity and disequilibrium as telltales of superconductivity","volume":"506","author":"Pennini","year":"2018","journal-title":"Physica A"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Cervia, M.J., Balantekin, A.B., Coppersmith, S.N., Johnson, C.W., Love, P.J., Poole, C., Robbins, K., and Saffman, M.
