Spurious Isospin Breaking in the In-medium Similarity Renormalization Group
A. Farren, S. R. Stroberg
Robustly quantifying the uncertainty in the isospin-related theoretical correction to superallowed beta decay rates is vital for a correct assessment of CKM unitarity. To thi…
Improving the predictive power of empirical shell-model Hamiltonians
J. A. Purcell, B. A. Brown, B. C. He +2
We present two developments which enhance the predictive power of empirical shell-model Hamiltonians for cases in which calibration data are sparse. A recent improvement in the ab…
Motivations for Early High-Profile FRIB Experiments
B. Alex Brown, Alexandra Gade, S. Ragnar Stroberg +39
This white paper is the result of a collaboration by those that attended a workshop at the Facility for Rare Isotope Beams (FRIB), organized by the FRIB Theory Alliance (FRIB-TA),…
Improved structure of calcium isotopes from ab initio calculations
M. Heinz, T. Miyagi, S. R. Stroberg +3
The in-medium similarity renormalization group (IMSRG) is a powerful and flexible many-body method to compute the structure of nuclei starting from nuclear forces. Recent developme…
Correlation of neutrinoless double-beta decay nuclear matrix elements with nucleon-nucleon phase shifts
A. Belley, J. Pitcher, T. Miyagi +2
We present an ab initio study of the correlation between nuclear matrix elements of neutrinoless double-beta () decay and nucleon-nucleon scattering phase shifts in the $^1S_…
IMSRG with flowing 3 body operators, and approximations thereof
S. R. Stroberg, T. D. Morris, B. C. He
We explore the impact of retaining three-body operators within the in-medium similarity renormalization group (IMSRG), as well as various approximations schemes. After studying two…
Factorized Approximation to the IMSRG(3)
B. C. He, S. R. Stroberg
We describe an approximation to the in-medium similarity renormalization group (IMSRG) method in which we include the effects of intermediate three-body operators arising within ne…
