Symbolic computation of the Hartree-Fock energy from a chiral EFT three-nucleon interaction at NLO
B. Gebremariam, S. K. Bogner, T. Duguet
We present the first of a two-part Mathematica notebook collection that implements a symbolic approach for the application of the density matrix expansion (DME) to the Hartree-Fock…
Symbolic integration of a product of two spherical bessel functions with an additional exponential and polynomial factor
B. Gebremariam, T. Duguet, S. K. Bogner
We present a mathematica package that performs the symbolic calculation of integrals of the form \int^{\infty}_0 e^{-x/u} x^n j_ν (x) j_μ (x) dx where and denot…
An improved density matrix expansion for spin-unsaturated nuclei
B. Gebremariam, T. Duguet, S. K. Bogner
A current objective of low-energy nuclear theory is to build non-empirical nuclear energy density functionals (EDFs) from underlying inter-nucleon interactions and many-body pertur…
Tensor part of the Skyrme energy density functional. II: Deformation properties of magic and semi-magic nuclei
M. Bender, K. Bennaceur, T. Duguet +3
We study systematically the impact of the time-even tensor terms of the Skyrme energy density functional, i.e. terms bilinear in the spin-current tensor density, on deformation pro…
Non-empirical nuclear energy functionals, pairing gaps and odd-even mass differences
T. Duguet, T. Lesinski
First, we briefly outline some aspects of the starting project to design non-empirical energy functionals based on low-momentum vacuum interactions and many-body perturbation theor…
Non-empirical pairing energy functional in nuclear matter and finite nuclei
K. Hebeler, T. Duguet, T. Lesinski +1
We study 1S0 pairing gaps in neutron and nuclear matter as well as in finite nuclei on the basis of microscopic two-nucleon interactions. Special attention is paid to the consisten…
