An extended Agassi model: algebraic structure, phase diagram, and large size limit
J. E. García-Ramos, J Dukelsky, P Pérez-Fernández +1
The Agassi model is a schematic two-level model that involves pairing and monopole-monopole interactions. It is, therefore, an extension of the well known Lipkin-Meshkov-Glick (LMG…

Critical point symmetries in boson-fermion systems. The case of shape transition in odd nuclei in a multi-orbit model
C. E. Alonso, J. M. Arias, A. Vitturi
We investigate phase transitions in boson-fermion systems. We propose an analytically solvable model (E(5/12)) to describe odd nuclei at the critical point in the transition from t…

Phase transitions in the Interacting Boson Fermion Model: the gamma-unstable case
C. E. Alonso, J. M. Arias, L. Fortunato +1
The phase transition around the critical point in the evolution from spherical to deformed gamma-unstable shapes is investigated in odd nuclei within the Interacting Boson Fermion…
