Low-rank matrix decompositions for ab initio nuclear structure
A. Tichai, P. Arthuis, K. Hebeler +3
The extension of ab initio quantum many-body theory to higher accuracy and larger systems is intrinsically limited by the handling of large data objects in form of wave-function ex…
ADG: Automated generation and evaluation of many-body diagrams III. Bogoliubov in-medium similarity renormalization group formalism
A. Tichai, P. Arthuis, H. Hergert +1
The goal of the present paper is twofold. First, a novel expansion many-body method applicable to superfluid open-shell nuclei, the so-called Bogoliubov in-medium similarity renorm…
ADG: Automated generation and evaluation of many-body diagrams II. Particle-number projected Bogoliubov many-body perturbation theory
P. Arthuis, A. Tichai, J. Ripoche +1
We describe the second version (v2.0.0) of the code ADG that automatically (1) generates all valid off-diagonal Bogoliubov many-body perturbation theory diagrams at play in particl…
Ab initio computation of charge densities for Sn and Xe isotopes
P. Arthuis, C. Barbieri, M. Vorabbi +1
We present the first ab initio calculations for open-shell nuclei past the tin isotopic line, focusing on Xe isotopes as well as doubly-magic Sn isotopes. We show that, even for mo…
ADG: Automated generation and evaluation of many-body diagrams I. Bogoliubov many-body perturbation theory
Pierre Arthuis, Thomas Duguet, Alexander Tichai +2
We describe the first version (v1.0.0) of the code ADG that automatically (1) generates all valid Bogoliubov many-body perturbation theory (BMBPT) diagrams and (2) evaluates their…
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…
