Entropies and IPR as Markers for a Phase Transition in a Two-Level Model for Atom-Diatomic Molecule Coexistence
Ignacio Baena, Pedro Pérez-Fernández, Manuela Rodríguez-Gallardo +1
A Quantum Phase Transition (QPT) in a simple model that describes the coexistence of atoms and diatomic molecules is studied. The model, that is briefly discussed, presents a secon…
Number conserving particle-hole RPA for superfluid nuclei
J. Dukelsky, J. E. García-Ramos, J. M. Arias +2
We present a number conserving particle-hole RPA theory for collective excitations in the transition from normal to superfluid nuclei. The method derives from an RPA theory develop…
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…
Phase diagram of an extended Agassi model
J. E. García-Ramos, J. Dukelsky, P. Pérez-Fernández +1
Background: The Agassi model is an extension of the Lipkin-Meshkov-Glick model that incorporates the pairing interaction. It is a schematic model that describes the interplay betwe…
