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…
Symmetry reduction of tensor networks in many-body theory I. Automated symbolic evaluation of algebra
Alexander Tichai, Roland Wirth, Julien Ripoche +1
The ongoing progress in (nuclear) many-body theory is accompanied by an ever-rising increase in complexity of the underlying formalisms used to solve the stationary Schrödinger equ…
Normal-ordered -body approximation in particle-number-breaking theories
Julien Ripoche, Alexander Tichai, Thomas Duguet
The reach of ab initio many-body theories is rapidly extending over the nuclear chart. However, dealing fully with three-nucleon, possibly four-nucleon, interactions makes the solv…
Pre-processing the nuclear many-body problem: Importance truncation versus tensor factorization techniques
Alexander Tichai, Julien Ripoche, Thomas Duguet
The solution of the nuclear A-body problem encounters severe limitations from the size of many-body operators. These limitations are typically related to both the (iterative) stori…
