Excited-state quantum phase transitions and chaos in a three-level Lipkin model
Alberto Mayorgas, Pedro Pérez-Fernández, Álvaro Sáiz +1
Excited-state quantum phase transitions (ESQPTs) have been extensively studied in two-level models, but their characterization remains challenging in systems displaying mixed regul…
The extended Lipkin model: proposal for implementation in a quantum platform and machine learning analysis of its phase diagram
S. Baid, A. Sáiz, L. Lamata +5
We investigate the Extended Lipkin Model (ELM), whose phase diagram mirrors that of the Interacting Boson Approximation model (IBA). Unlike the standard Lipkin model, the ELM (as t…
A digital quantum simulation of the Agassi model
Pedro Pérez-Fernández, José Miguel Arias, José Enrique García-Ramos +1
A digital quantum simulation of the Agassi model from nuclear physics is proposed and analyzed. The proposal is worked out for the case with four different sites. Numerical simulat…
