Emulating \emph{ab initio} computations of infinite nucleonic matter
W. G. Jiang, C. Forssén, T. Djärv +1
We construct efficient emulators for the \emph{ab initio} computation of the infinite nuclear matter equation of state. These emulators are based on the subspace-projected coupled-…
Nuclear-matter saturation and symmetry energy within --full chiral effective field theory
W. G. Jiang, C. Forssén, T. Djärv +1
Nuclear saturation and the symmetry energy are key properties of low-energy nuclear physics that depend on fine details of the nuclear interaction. The equation-of-state around sat…
What is ab initio in nuclear theory?
A. Ekström, C. Forssén, G. Hagen +3
Ab initio has been used as a label in nuclear theory for over two decades. Its meaning has evolved and broadened over the years. We present our interpretation, briefly review its h…
Gamow-Teller strengths from unstable O via the reaction in inverse kinematics
S. Giraud, J. C. Zamora, R. Zegers +24
For the first time, the reaction was successfully used in inverse kinematics to extract the Gamow-Teller transition strength in the direction from an un…
Proton distribution radii of O: signatures of new shell closures and neutron skin
S. Kaur, R. Kanungo, W. Horiuchi +38
The root mean square radii of the proton density distribution in O derived from measurements of charge changing cross sections with a carbon target at 900 MeV to…
Towards Precise and Accurate Calculations of Neutrinoless Double-Beta Decay: Project Scoping Workshop Report
V. Cirigliano, Z. Davoudi, J. Engel +20
We present the results of a National Science Foundation (NSF) Project Scoping Workshop, the purpose of which was to assess the current status of calculations for the nuclear matrix…
How to renormalize coupled cluster theory
Z. H. Sun, C. A. Bell, G. Hagen +1
Coupled cluster theory is an attractive tool to solve the quantum many-body problem because its singles and doubles (CCSD) approximation is computationally affordable and yields ab…
Spectral function for He using the Chebyshev expansion in coupled-cluster theory
J. E. Sobczyk, S. Bacca, G. Hagen +1
We compute spectral function for He by combining coupled-cluster theory with an expansion of integral transforms into Chebyshev polynomials. Our method allows to estimate the u…
Systematics of E2 strength in the sd-shell with the valence-space in-medium similarity renormalization group
S. R. Stroberg, J. Henderson, G. Hackman +3
Background: Recent developments in {\it ab initio} nuclear theory demonstrate promising results in medium- to heavy-mass nuclei. A particular challenge for many of the many-body me…
Angular-momentum projection in coupled-cluster theory: structure of Mg
G. Hagen, S. J. Novario, Z. H. Sun +5
Single-reference coupled-cluster theory is an accurate and affordable computational method for the nuclear many-body problem. For open-shell nuclei, the reference state typically b…
