Improved many-body expansions from eigenvector continuation
Pepijn Demol, Thomas Duguet, Andreas Ekström +7
Quantum many-body theory has witnessed tremendous progress in various fields, ranging from atomic and solid-state physics to quantum chemistry and nuclear structure. Due to the inh…
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…
