Magnetic dipole transition in Ca
B. Acharya, B. S. Hu, S. Bacca +3
The magnetic dipole transition strength of Ca is dominated by a single resonant state at an excitation energy of 10.23 MeV. Experiments disagree about and th…
Scattering phase shifts from a quantum computer
Sanket Sharma, Thomas Papenbrock, Lucas Platter
We calculate two-body scattering phase shifts on a quantum computer using a leading order short-range effective field theory Hamiltonian. The algorithm combines the variational qua…
Surprising charge-radius kink in the Sc isotopes at N=20
Kristian König, Stephan Fritzsche, Gaute Hagen +11
Charge radii of neutron deficient 40Sc and 41Sc nuclei were determined using collinear laser spectroscopy. With the new data, the chain of Sc charge radii extends below the neutron…
Coupled-cluster theory for strong entanglement in nuclei
Z. H. Sun, G. Hagen, T. Papenbrock
Atomic nuclei can exhibit shape coexistence and multi-reference physics that enters in their ground states, and to accurately capture the ensuing correlations and entanglement is c…
How chiral forces shape neutron-rich Ne and Mg nuclei
Andreas Ekström, Christian Forssén, G. Hagen +3
We compute the structure of the exotic even nuclei Ne and Mg using interactions from chiral effective field theory (EFT). Our results for the ground-state rotat…
Entanglement entropy of nuclear systems
Chenyi Gu, Z. H. Sun, G. Hagen +1
We study entanglement entropies between the single-particle states of the hole space and its complement in nuclear systems. Analytical results based on the coupled-cluster method s…
