HFBTHO-AD: Differentiation of a nuclear energy density functional code
Laurent Hascoët, Matt Menickelly, Sri Hari Krishna Narayanan +3
The HFBTHO code implements a nuclear energy density functional solver to model the structure of atomic nuclei. HFBTHO has previously been used to calibrate energy functionals and p…

A nuclear mass model rooted in chiral effective field theory
C. Mishra, A. Ekström, G. Hagen +3
We develop a nuclear mass model that is based on chiral effective field theory at next-to-next-to leading order. Nuclear binding energies are computed via the Hartree-Fock method u…

ReMU: Regional Minimal Updating for Model-Based Derivative-Free Optimization
Pengcheng Xie, Stefan M. Wild
Derivative-free optimization (DFO) problems are optimization problems where derivative information is unavailable or extremely difficult to obtain. Model-based DFO solvers have bee…
