Ab Initio Path to Heavy Nuclei
Sven Binder, Joachim Langhammer, Angelo Calci +1
We present the first ab initio calculations of nuclear ground states up into the domain of heavy nuclei, spanning the range from 16-O to 132-Sn based on two- plus three-nucleon int…
Evolved Chiral NN+3N Hamiltonians for Ab Initio Nuclear Structure Calculations
Robert Roth, Angelo Calci, Joachim Langhammer +1
We discuss the building blocks for a consistent inclusion of chiral three-nucleon (3N) interactions into ab initio nuclear structure calculations beyond the lower p-shell. We highl…
Extension of coupled-cluster theory with a non-iterative treatment of connected triply excited clusters to three-body Hamiltonians
Sven Binder, Piotr Piecuch, Angelo Calci +3
We generalize the coupled-cluster (CC) approach with singles, doubles, and the non-iterative treatment of triples termed CCSD(T) to Hamiltonians containing three-body interactio…
Ab Initio Calculations of Even Oxygen Isotopes with Chiral Two- Plus Three-Nucleon Interactions
H. Hergert, S. Binder, A. Calci +2
We formulate the In-Medium Similarity Renormalization Group (IM-SRG) for open-shell nuclei using a multi-reference formalism based on a generalized Wick theorem introduced in quant…
