The nucleon-pair approximation for nuclei from spherical to deformed regions
G. J. Fu, Calvin W. Johnson
In this paper we model low-lying states of atomic nuclei in the nucleon-pair approximation of the shell model, using three approaches to select collective nucleon pairs: the genera…
Rotational bands beyond the Elliott model
Ryan Zbikowski, Calvin W. Johnson, Anna E. McCoy +2
Rotational bands are commonplace in the spectra of atomic nuclei. Inspired by early descriptions of these bands by quadrupole deformations of a liquid drop, Elliott constructed a d…
Lipkin model on a quantum computer
Michael J. Cervia, A. B. Balantekin, S. N. Coppersmith +5
Atomic nuclei are important laboratories for exploring and testing new insights into the universe, such as experiments to directly detect dark matter or explore properties of neutr…
Exact sum rules with approximate ground states
Calvin W. Johnson, Ken A. Luu, Yi Lu
Electromagnetic and weak transitions tell us a great deal about the structure of atomic nuclei. Yet modeling transitions can be difficult: it is often easier to compute the ground…
