Astrophysical reaction rate for 9 Be formation within a three-body approach
(American Physical Society, 2014)
The structure of the Borromean nucleus 9Be (α+α+n) is addressed within a three-body approach using the analytical transformed harmonic oscillator method. The three-body formalism provides an accurate description of the ...

Be 9 + Sn 120 scattering at near-barrier energies within a four-body model
(American Physical Society, 2018)
Cross sections for elastic and inelastic scattering of the weakly bound Be9 nucleus on a Sn120 target have been measured at seven bombarding energies around and above the Coulomb barrier. The elastic angular distributions ...

Review of Shape Phase Transition Studies for Bose-Fermi Systems: The Effect of the Odd-Particle on the Bosonic Core
(MDPI, 2021-01)
The quantum phase transition studies we have done during the last few years for odd-even systems are reviewed. The focus is on the quantum shape phase transition in Bose-Fermi systems. They are studied within the Interacting ...

Nuclear Shape-Phase Transitions and the Sextic Oscillator
(MDPI, 2023-11-14)
This review delves into the utilization of a sextic oscillator within the 𝛽 degree of freedom of the Bohr Hamiltonian to elucidate critical-point solutions in nuclei, with a specific emphasis on the critical point associated ...

Excited-state quantum phase transitions in a two-fluid Lipkin model
(American Physical Society, 2017-05-30)
Background: Composed systems have become of great interest in the framework of ground-state quantum phase transitions (QPTs) and many of their properties have been studied in detail. However, in these systems, the study ...

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 ...

Improved di-neutron cluster model for 6 He scattering
(American Physical Society, 2007)
The structure of the three-body Borromean nucleus He6 is approximated by a two-body di-neutron cluster model. The binding energy of the 2n-α system is determined to obtain a correct description of the 2n-α coordinate, as ...

A digital quantum simulation of the Agassi model
(Elsevier, 2022)
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 simulations and analytical estimations are presented ...
