Quasidynamical Symmetry in an Interacting Boson Model Phase Transition
Quasidynamical Symmetry in an Interacting Boson Model Phase Transition
The apparent persistence of symmetry in the face of strong symmetry-breaking interactions is examined in a many-boson model. The model exhibits a transition between two phases associated with U(5) and O(6) symmetries, respectively, as the value of a control parameter progresses from 0 to 1. The remarkable fact is that, …
