Ab initio studies of double Gamow-Teller transition and its correlation with neutrinoless double beta decay
J. M. Yao, I. Ginnett, A. Belley +7
We use chiral interactions and several {\em ab initio} methods to compute the nuclear matrix elements (NMEs) for ground-state to ground-state double Gamow-Teller transitions in a r…
No-Core Shell Model for Nuclear Systems with Strangeness
D. Gazda, J. Mareš, P. Navrátil +2
We report on a novel ab initio approach for nuclear few- and many-body systems with strangeness. Recently, we developed a relevant no-core shell model technique which we successful…
Singular Value Decomposition and Similarity Renormalization Group Evolution of Nuclear Interactions
B. Zhu, R. Wirth, H. Hergert
One of the main challenges for ab initio nuclear many-body theory is the growth of computational and storage costs as calculations are extended to heavy, exotic, and structurally c…
Ab Initio Treatment of Collective Correlations and the Neutrinoless Double Beta Decay of Ca
J. M. Yao, B. Bally, J. Engel +3
Working with Hamiltonians from chiral effective field theory, we develop a novel framework for describing arbitrary deformed medium-mass nuclei by combining the in-medium similarit…
Modewise Johnson-Lindenstrauss Embeddings for Nuclear Many-Body Theory
A. Zare, R. Wirth, C. A. Haselby +2
In this work, we explore modewise Johnson-Lindenstrauss embeddings (JLEs) as a tool to reduce the computational cost and memory requirements of nuclear many-body methods. JLEs are…
Ab initio calculation of the contact operator contribution in the standard mechanism for neutrinoless double beta decay
R. Wirth, J. M. Yao, H. Hergert
Starting from chiral nuclear interactions, we evaluate the contribution of the leading-order contact transition operator to the nuclear matrix element (NME) of neutrinoless double-…
