Emulators for low-energy nuclear physics can provide fast and accurate predictions of
bound-state and scattering observables for applications that require repeated calculations …

We construct an efficient emulator for two-body scattering observables using the general
(complex) Kohn variational principle and trial wave functions derived from eigenvector …

Energy-dependent and single-energy fits to the existing nucleon-nucleon database have
been updated to incorporate recent measurements. The fits cover a region from threshold to …

For laboratory kinetic energies between 50 and 200 MeV, we focus on generating an energy-
dependent Lorentz covariant parametrization of the on-shell nucleon-nucleon (NN) …

Background: Calculating microscopic effective interactions (optical potentials) for elastic
nucleon-nucleus scattering has already led to a large body of work. For leading-order …

We consider nucleon-nucleon (NN) interactions from chiral effective field theory applying the
N/D method. The dynamical input is given by the discontinuity of the NN partial-wave …

Background: In a previous series of papers we investigated the domain of applicability of
chiral potentials to the construction of a microscopic optical potential (OP) for elastic nucleon …

We extend earlier work on analytic evaluations of nucleon scattering amplitudes to the Dirac
treatment. The resulting closed form expressions are accurate and show how the two-body …

In this work we present a framework that allows one to solve the Faddeev equations for three-
nucleon scattering using the wave-packet continuum-discretization method. We perform …

Eigenvector continuation (EC) has been shown to accurately and efficiently reproduce
ground states for targeted sets of Hamiltonian parameters. It uses as variational basis …
