2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/81738We review recent results obtained in numerical studies of the nuclear shell model and the interacting boson model with random interactions, in particular the dominance of ground states with L=0 and the occurrence of vibrational and rotational bands. We discuss some possible explanations of the origin of these regular features.12 pages, 4 figures, 1 table. Nuclear Physics News, in pressNuclear TheoryChaotic Dynamicstext
