Criticality in the configuration-mixed interacting boson model : (1) U(5)-Q()·Q() mixing
Abstract
The case of U(5)--Q()·Q() mixing in the configuration-mixed Interacting Boson Model is studied in its mean-field approximation. Phase diagrams with analytical and numerical solutions are constructed and discussed. Indications for first-order and second-order shape phase transitions can be obtained from binding energies and from critical exponents, respectively.
