Entropies and IPR as Markers for a Phase Transition in a Two-Level Model for Atom–Diatomic Molecule Coexistence
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
A quantum phase transition (QPT) in a simple model that describes the coexistence of atoms and diatomic molecules is studied. The model, which is briefly discussed, presents a second-order ground state phase transition in ...

Algebraic DVR Approaches Applied to Describe the Stark Effect
(MDPI, 2020)
Two algebraic approaches based on a discrete variable representation are introduced and applied to describe the Stark effect in the non-relativistic Hydrogen atom. One approach consists of considering an algebraic ...

Digital quantum simulation of an extended Agassi model: Using machine learning to disentangle its phase-diagram
(American Physical Society, 2022)
A digital quantum simulation for the extended Agassi model is proposed using a quantum platform with eight trapped ions. The extended Agassi model is an analytically solvable model including both short range pairing and ...
