The one nucleon transfer operator in the microscopic IBM without NOA
(Elsevier, 2014)
The mapping of the single fermion creation operator (ci†) onto the Interacting Boson-Fermion space (IBFM) is revisited within the Generalized Seniority scheme. In the original work the Number Operator Approximation (NOA) ...

Determining astrophysical three-body radiative capture reaction rates from inclusive Coulomb break-up measurements
(American Physical Society, 2016-04-12)
A relationship between the Coulomb inclusive break-up probability and the radiative capture reaction rate for weakly bound three-body systems is established. This direct link provides a robust procedure to estimate the ...

Analytical transformed harmonic oscillator basis for three-body nuclei of astrophysical interest: Application to 6He
(American Physical Society, 2013-06-29)
Recently, a square-integrable discrete basis, obtained performing a simple analytical local scale transformation to the harmonic oscillator basis, has been proposed and successfully applied to study the properties of ...

Excited-state Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model: Dynamical Aspects
(American Physical Society, 2023)
The standard Lipkin-Meshkov-Glick (LMG) model undergoes a second-order ground-state quantum phase transition (QPT) and an excited-state quantum phase transition (ESQPT). The inclusion of an anharmonic term in the LMG ...

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 ...
