Medium-Mass and Heavy Nuclei from Chiral NN+3N Hamiltonians — •Sven Binder, Joachim Langhammer, Angelo Calci, and Robert Roth — TU Darmstadt

We present ab initio calculations of nuclear binding energies using chiral two- plus three-nucleon Hamiltonians evolved consistently with the similarity renormalization group. We use coupled-cluster theory at the singles and doubles excitations level in combination with a non-iterative treatment of triples excitations in order to obtain accurate solutions of the many-body problem. We explore different chiral two- and three-nucleon interactions and the systematics of ground-state energies up to 132-Sn. These calculations open the door to ab initio calculations in the regime of heavy nuclei and demonstrate the predictive power of chiral Hamiltonians.
