Novel chiral Hamiltonian and observables in light and medium-mass nuclei
V. Somà, P. Navrátil, F. Raimondi +2
A novel parameterisation of a Hamiltonian based on chiral effective field theory is introduced. Specifically, three-nucleon operators at next-to-next-to-leading order are combined…
Nuclear electromagnetic dipole response with the Self-Consistent Green's Function formalism
F. Raimondi, C. Barbieri
Microscopic calculations of the electromagnetic response of medium-mass nuclei are now feasible thanks to the availability of realistic nuclear interactions with accurate saturatio…
Core-polarization effects and effective charges in O and Ni isotopes from chiral interactions
Francesco Raimondi, Carlo Barbieri
Most nuclear structure calculations, even for full configuration interaction approaches, are performed within truncated model spaces. These require consistent transformations of th…
Recent Applications of Self-Consistent Green's Function Theory to Nuclei
Carlo Barbieri, Francesco Raimondi, Christopher McIlroy
We discuss recent \emph{ab initio} calculations based on self-consistent Green's function theory. It is found that a simple extension of the formalism to account for two-nucleon sc…
Algebraic diagrammatic construction formalism with three-body interactions
Francesco Raimondi, Carlo Barbieri
Self-consistent Green's function theory has recently been extended to the basic formalism needed to account for three-body interactions [A. Carbone, A. Cipollone, C. Barbieri, A. R…
Li(,)Li transfer reaction in the NCSM/RGM approach
F. Raimondi, G. Hupin, P. Navrátil +1
Recently, we applied an method, the no-core shell model combined with the resonating group method, to the transfer reactions with light p-shell nuclei as targets and…
Irreducible 3-body forces contributions to the self-energy
F. Raimondi, C. Barbieri
The inclusion of the three-nucleon forces (3NFs) in \textit{ab initio} many-body approaches is a formidable task, due to the computational load implied by the treatment of their ma…
Nonlocal energy density functionals for pairing and beyond-mean-field calculations
K. Bennaceur, A. Idini, J. Dobaczewski +3
We propose to use two-body regularized finite-range pseudopotential to generate nuclear energy density functional (EDF) in both particle-hole and particle-particle channels, which…
Deuteron-induced nucleon transfer reactions within an ab initio framework: First application to p-shell nuclei
Francesco Raimondi, Guillaume Hupin, Petr Navrátil +1
Background: Low-energy transfer reactions in which a proton is stripped from a deuteron projectile and dropped into a target play a crucial role in the formation of nuclei in both…
and astrophysical factors from the no-core shell model with continuum
Jérémy Dohet-Eraly, Petr Navrátil, Sofia Quaglioni +3
The and astrophysical factors are calculated within the no-core shell model with continuum using a renormalized c…
Nonlocal energy density functionals for low-energy nuclear structure
F. Raimondi, K. Bennaceur, J. Dobaczewski
We introduce a finite-range pseudopotential built as an expansion in derivatives up to next-to-next-to-next-to-leading order (NLO) and we calculate the corresponding nonlocal e…
New density-independent interactions for nuclear structure calculations
K. Bennaceur, J. Dobaczewski, F. Raimondi
We present a new two-body finite-range and momentum-dependent but density-independent effective interaction, which can be interpreted as a regularized zero-range force. We show tha…
Effective theory for low-energy nuclear energy density functionals
J. Dobaczewski, K. Bennaceur, F. Raimondi
We introduce a new class of effective interactions to be used within the energy-density-functional approaches. They are based on regularized zero-range interactions and constitute…
Continuity equation and local gauge invariance for the N3LO nuclear Energy Density Functionals
F. Raimondi, B. G. Carlsson, J. Dobaczewski +1
Background: The next-to-next-to-next-to-leading order (N3LO) nuclear energy density functional extends the standard Skyrme functional with new terms depending on higher-order deriv…
Effective pseudopotential for energy density functionals with higher order derivatives
F. Raimondi, B. G. Carlsson, J. Dobaczewski
We derive a zero-range pseudopotential that includes all possible terms up to sixth order in derivatives. Within the Hartree-Fock approximation, it gives the average energy that co…
