Gorkov algebraic diagrammatic construction formalism at third order
Carlo Barbieri, Thomas Duguet, Vittorio Somà
Background. The Gorkov approach to self-consistent Green's function theory has been formulated in [V. Somà, T. Duguet, C. Barbieri, Phys. Rev. C 84, 064317 (2011)]. Over the past d…
Multi-reference many-body perturbation theory for nuclei III -- Ab initio calculations at second order in PGCM-PT
Mikael Frosini, Thomas Duguet, Jean-Paul Ebran +6
In spite of missing dynamical correlations, the projected generator coordinate method (PGCM) was recently shown to be a suitable method to tackle the low-lying spectroscopy of comp…
Multi-reference many-body perturbation theory for nuclei II -- Ab initio study of neon isotopes via PGCM and IM-NCSM calculations
Mikael Frosini, Thomas Duguet, Jean-Paul Ebran +5
The neon isotopic chain displays a rich phenomenology, ranging from clustering in the ground-state of the self-conjugate doubly open-shell stable Ne isotope to the physics o…
Multi-reference many-body perturbation theory for nuclei I -- Novel PGCM-PT formalism
Mikael Frosini, Thomas Duguet, Jean-Paul Ebran +1
Perturbative and non-perturbative expansion methods already constitute a tool of choice to perform ab initio calculations over a significant part of the nuclear chart. In this cont…
In-medium -body reduction of -body operators
Mikael Frosini, Thomas Duguet, Benjamin Bally +3
The computational cost of ab initio nuclear structure calculations is rendered particularly acute by the presence of (at least) three-nucleon interactions. This feature becomes esp…
Accessing the shape of atomic nuclei with relativistic collisions of isobars
Giuliano Giacalone, Jiangyong Jia, Vittorio Somà
Nuclides sharing the same mass number (isobars) are observed ubiquitously along the stability line. While having nearly identical radii, stable isobars can differ in shape, and pre…
