Few- and many-nucleon systems with semilocal coordinate-space regularized chiral nucleon-nucleon forces
S. Binder, A. Calci, E. Epelbaum +15
We employ a variety of ab initio methods including Faddeev-Yakubovsky equations, No-Core Configuration Interaction Approach, Coupled-Cluster Theory and In-Medium Similarity Renorma…
Pion-less effective field theory for atomic nuclei and lattice nuclei
A. Bansal, S. Binder, A. Ekström +3
We compute the medium-mass nuclei O and Ca using pionless effective field theory (EFT) at next-to-leading order (NLO). The low-energy coefficients of the EFT Hamilton…
Hartree-Fock Many-Body Perturbation Theory for Nuclear Ground-States
Alexander Tichai, Joachim Langhammer, Sven Binder +1
We investigate the order-by-order convergence behavior of many-body perturbation theory (MBPT) as a simple and efficient tool to approximate the ground-state energy of closed-shell…
Effective field theory in the harmonic oscillator basis
S. Binder, A. Ekström, G. Hagen +2
We develop interactions from chiral effective field theory (EFT) that are tailored to the harmonic oscillator basis. As a consequence, ultraviolet convergence with respect to the m…
Ab Initio No Core Shell Model - Recent Results and Further Prospects
