Two-neutron transfer reactions as a tool to study the interplay between shape coexistence and quantum phase transitions
J. E. García-Ramos, J. M. Arias, A. Vitturi
The goal of this study is to find an observable that could distinguish between both phenomena, shape coexistence and quantum phase transitions. The selected observable to be analyz…
Excited-state quantum phase transitions in a two-fluid Lipkin model
J. E. Garcia-Ramos, P. Perez-Fernandez, J. M. Arias
Background: Composed systems have became of great interest in the framework of the ground state quantum phase transitions (QPTs) and many of their properties have been studied in d…
Phase diagram of the two-fluid Lipkin model: a butterfly catastrophe
J. E. García-Ramos, P. Pérez-Fernandez, J. M Arias +1
Background: In the last few decades quantum phase transitions have been of great interest in Nuclear Physics. In this context, two-fluid algebraic models are ideal systems to study…
Relationship between X(5)-models and the interacting boson model
J. Barea, J. M. Arias, J. E. García-Ramos
The connections between the X(5)-models (the original X(5) using an infinite square well, X(5)-, X(5)-, X(5)-, and X(5)-), based on particular solutions of the…
