Universal reduced order modelling for the nuclear finite amplitude method

Emma Vancayseele, Pepijn Demol, Luis González-Miret Zaragoza +2

The quasiparticle random phase approximation or QRPA has been a foundational many-body technique for decades across quantum chemistry, condensed matter and nuclear physics. Althoug…

Balancing theory uncertainties in ab initio nuclear structure calculations: Many-body truncation versus finite basis size

L. Zurek, U. Vernik, P. Demol +3

First-principles calculations of atomic nuclei are necessarily incomplete as the Schrödinger equation is solved using approximate methods and due to the finite dimension of the emp…

High-precision ab initio calculations of nuclear binding energies: Tin isotopes from dripline to dripline

Urban Vernik, Pepijn Demol, Thomas Duguet +1

The location of the neutron drip line in tin isotopes has important consequences for our fundamental understanding of nuclear structure and nuclear forces as well as for astrophysi…

Ab initio Bogoliubov many-body perturbation theory: closed-form constraint on the average particle number

Pepijn Demol, Thomas Duguet, Alexander Tichai

Bogoliubov many-body perturbation theory (BMBPT) relying on the breaking of U(1) global gauge symmetry has been recently formulated and applied to extend the applicability of stand…

Impact of correlations on nuclear binding energies

Alberto Scalesi, Thomas Duguet, Pepijn Demol +3

A strong effort will be dedicated in the coming years to extend the reach of ab initio nuclear-structure calculations to heavy doubly open-shell nuclei. In order to do so, the most…

Bogoliubov many-body perturbation theory under constraint

Pepijn Demol, Mikael Frosini, Alexander Tichai +2

In order to solve the A-body Schrödinger equation both accurately and efficiently for open-shell nuclei, a novel many-body method coined as Bogoliubov many-body perturbation theory…
