Symmetry Remnants in the Face of Competing Interactions in Nuclei

TL;DR

This paper explores how partial and quasi dynamical symmetries can persist in nuclei during shape-phase transitions despite complex interactions that break traditional symmetries.

Contribution

It introduces the application of generalized dynamical symmetries to understand nuclear shape-phase transitions amid symmetry-breaking interactions.

Findings

Partial and quasi dynamical symmetries can describe subsets of nuclear states.

These symmetries provide insight into nuclear shape-phase transitions.

The approach helps reconcile model Hamiltonians with observed nuclear behaviors.

Abstract

Detailed description of nuclei necessitates model Hamiltonians which break most dynamical symmetries. Nevertheless, generalized notions of partial and quasi dynamical symmetries may still be applicable to selected subsets of states, amidst a complicated environment of other states. We examine such scenarios in the context of nuclear shape-phase transitions.
