A practical approach to perturbative corrections to few-body observables
Sourav Mondal, Martin Schäfer, Mirko Bagnarol +3
We formulate two methods to facilitate the calculation of perturbative corrections to quantum few-body observables. Both techniques are designed for a numerical realization in comb…

Accurate calculation of low energy scattering phase shifts of charged particles in a harmonic oscillator trap
Mirko Bagnarol, Nir Barnea, Matus Rojik +1
Considering the elastic scattering of two charged particles, we present two methods for numerically solving the generalized Coulomb-corrected BERW formula with high accuracy across…

Five-body calculation of -wave -He scattering at next-to-leading order pionless effective field theory
Mirko Bagnarol, Martin Schäfer, Betzalel Bazak +1
We present the first five-body calculations of -wave -He scattering within leading order and next-to-leading order (NLO) pionless effective field theory. Using an harmoni…
