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…
Towards nuclear energy density functionals from first principles
Lars Zurek
We discuss the GUDE functionals which consist of pion exchanges derived from chiral effective field theory and a Skyrme-like part. Certain pion terms lead to significant improvemen…
Mean-field approximation on steroids: exact description of the deuteron
B. Bally, A. Scalesi, V. Somà +2
The present article demonstrates that the deuteron, i.e. the lightest bound nuclear system made of a single proton and a single neutron, can be accurately described within a mean-f…
Dimensionality reduction through tensor factorization : application to \textit{ab initio} nuclear physics calculations
Mikael Frosini, Thomas Duguet, Pierre Tamagno +1
The construction of predictive models of atomic nuclei from first principles is a challenging (yet necessary) task towards the systematic generation of theoretical predictions (and…
