Ab initio Green's functions approach for homogeneous nuclear matter
Francesco Marino, Carlo Barbieri, Gianluca Colò +2
Homogeneous nuclear matter is investigated using the \textit{ab initio} Self-consistent Green's function (SCGF) approach with nuclear interactions based on chiral effective field t…
Ab initio calculation of the potential bubble nucleus Si
T. Duguet, V. Somà, S. Lecluse +2
The possibility that an unconventional depletion in the center of the charge density distribution of certain nuclei occurs due to a purely quantum mechanical effect has attracted t…
Chiral three-nucleon forces and the evolution of correlations along the oxygen isotopic chain
A. Cipollone, C. Barbieri, P. Navrátil
The impact of three-nucleon forces (3NFs) along the oxygen chain is investigated for the spectral distribution for attachment and removal of a nucleon, spectroscopic factors and ma…
Many-body Propagator Theory with Three-Body Interactions: a Path to Exotic Open Shell Isotopes
C. Barbieri
Ab-initio predictions of nuclei with masses up to A~100 or more is becoming possible thanks to novel advances in computations and in the formalism of many-body physics. Some of the…
Ab-initio self-consistent Gorkov-Green's function calculations of semi-magic nuclei - II. Numerical implementation at second order with a two-nucleon interaction
V. Soma, C. Barbieri, T. Duguet
The newly developed Gorkov-Green's function approach represents a promising path to the ab initio description of medium-mass open-shell nuclei. We discuss the implementation of the…
Nuclear astrophysics with radioactive ions at FAIR
R. Reifarth, S. Altstadt, K. Göbel +317
The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those proces…
Three-nucleon forces in exotic open-shell isotopes
V. Soma, C. Barbieri, A. Cipollone +2
Advances in the self-consistent Green's function approach to finite nuclei are discussed, including the implementation of three-nucleon forces and the extension to the Gorkov forma…
Isotopic chains around oxygen from evolved chiral two- and three-nucleon interactions
Andrea Cipollone, Carlo Barbieri, Petr Navrátil
We extend the formalism of self-consistent Green's function theory to include three-body interactions and apply it to isotopic chains around oxygen for the first time. The third-or…
Ab-initio Gorkov-Green's function calculations of open-shell nuclei
V. Soma, C. Barbieri, T. Duguet
We present results from a new ab-initio method that uses the self-consistent Gorkov Green's function theory to address truly open-shell systems. The formalism has been recently wor…
Ab-initio self-consistent Gorkov-Green's function calculations of semi-magic nuclei - I. Formalism at second order with a two-nucleon interaction
V. Soma, T. Duguet, C. Barbieri
An ab-initio calculation scheme for finite nuclei based on self-consistent Green's functions in the Gorkov formalism is developed. It aims at describing properties of doubly-magic…
Microscopic self-energy calculations and dispersive optical-model potentials
S. J. Waldecker, C. Barbieri, W. H. Dickhoff
Nucleon self-energies for 40Ca, 48Ca, 60Ca isotopes are generated with the microscopic Faddeev-random-phase approximation (FRPA). These self-energies are compared with potentials f…
Role of Long-Range Correlations on the Quenching of Spectroscopic Factors
C. Barbieri
We consider the proton and neutron quasiparticle orbits around the closed-shell 56Ni and 48Ca isotopes. It is found that large model spaces (beyond the capability of shell-model ap…
Toward a Global Dispersive Optical Model for the Driplines
C. Barbieri, R. J. Charity, W. H. Dickhoff +1
A dispersive-optical-model analysis has been performed for both protons and neutrons on 40,42,44,48Ca isotopes. The fitted potentials describe accurately both scattering and bound…
