The iconic U: ab initio nuclear structure theory towards the limit of the periodic table
A. Scalesi, T. Duguet, V. Somà
The ab initio description of heavy and superheavy nuclei constitutes one of the holy grails of nuclear theory, bearing on the synthesis of the heaviest elements and the limits of n…

Deformed self-consistent Green's function method for atomic nuclei at second and third order in the algebraic diagrammatic construction
A. Scalesi, T. Duguet, V. Somà
The description of atomic nuclei from first principles constitutes one of the central goals of nuclear theory. Polynomial-scaling expansion methods have extended \textit{ab initio}…

Bogoliubov Many-Body Perturbation Theory for Open-Shell Nuclei
Alexander Tichai, Pierre Arthuis, Thomas Duguet +3
A novel Rayleigh-Schrödinger many-body perturbation theory (MBPT) approach is introduced by making use of a particle-number-breaking Bogoliubov reference state to tackle (near-)deg…
