Phase diagram of the two-fluid Lipkin model : a "butterfly" catastrophe
García Ramos, José Enrique; Pérez Fernández, Pedro; Arias Carrasco, José Miguel; Freire, Emilio (American Physical Society, 2016)
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 how the concept of quantum phase transition ... -
Quantum Phase Transitions in Coupled Systems : an application of Catastrophe Theory
Two-fluid algebraic models are of great interest in the context of quantum phase transition in nuclei. We intend to study the phase diagram of a two-fluid Lipkin model that resembles a nuclear proton-neutron interacting ...
