Laser spectroscopy illuminates the shell closure
Tim E. Lellinger, Liss V. Rodriguez, Patrick Muller +29
Atomic nuclei are strongly correlated quantum many-body systems, and how their shell structure evolves with increasing neutron excess remains a central open question in nuclear phy…
Two-neutrino double-weak decays of Xe and Xe from different many-body methods
C. Brase, L. Jokiniemi, E. Kauppinen +4
We calculate the nuclear matrix elements and corresponding half-lives for the two-neutrino double-electron capture of Xe and the two-neutrino double-beta decay of X…
Ab initio calculations of two-neutrino and neutrinoless double- decay of Ca and related Gamow-Teller strength distributions
Zhen Li, Lotta Jokiniemi, Achim Schwenk
We present ab initio calculations of two-neutrino double-beta () decay of Ca and the related Gamow-Teller (GT) strength functions in Sc using the valence-space…
Uncertainties with low-resolution nuclear forces
Tom Plies, Matthias Heinz, Achim Schwenk
Low-resolution nuclear Hamiltonians, obtained from chiral effective field theory (EFT) and softened using renormalization group techniques, have been very successful in nuclear str…
Ab initio calculations of beta-decay half-lives for neutron-rich nuclei
Zhen Li, Takayuki Miyagi, Achim Schwenk
Beta-decay rates of extreme neutron-rich nuclei remain largely unknown experimentally, while they are critical inputs for -process nucleosynthesis. We present first ab initio ca…
Connecting Relativistic Density Functional Theory to Microscopic Calculations
Brendan T. Reed, Matthias Heinz, Pierre Arthuis +2
The development of systematic effective field theories (EFTs) for nuclear forces and advances in solving the nuclear many-body problem have greatly improved our understanding of de…
Ab initio calculations of overlap integrals for conversion in nuclei
Matthias Heinz, Martin Hoferichter, Takayuki Miyagi +2
The rate for conversion in nuclei is set to provide the most stringent test of lepton-flavor symmetry and a window into physics beyond the Standard Model. However, to dise…
Gamow-Teller and double-beta decays of heavy nuclei within an effective theory
Eduardo Antonio Coello Pérez, Javier Menéndez, Achim Schwenk
We study decays within an effective theory that treats nuclei as a spherical collective core with an even number of neutrons and protons that can couple to an additional neutro…
Large-scale nuclear structure calculations for spin-dependent WIMP scattering with chiral effective field theory currents
P. Klos, J. Menéndez, D. Gazit +1
We perform state-of-the-art large-scale shell-model calculations of the structure factors for elastic spin-dependent WIMP scattering off 129,131Xe, 127I, 73Ge, 19F, 23Na, 27Al, and…
Role of three-nucleon forces and many-body processes in nuclear pairing
J. D. Holt, J. Menendez, A. Schwenk
We present microscopic valence-shell calculations of pairing gaps in the calcium isotopes, focusing on the role of three-nucleon (3N) forces and many-body processes. In most cases,…
