Deformation-driven intruder states in light island-of-inversion nuclei
Calvin W. Johnson, Mark A. Caprio, Shwetha L. Vittal
Islands of inversion occur when the nuclear ground state is dominated by intruder configurations, specifically particle-hole excitations across shell gaps, rather than by the naive…
Ab-initio calculation of the photonuclear cross section of B
M. K. G. Kruse, W. E. Ormand, C. W. Johnson
We present for the first-time the photonuclear cross section of B calculated within the ab-initio No Core Shell Model framework. Realistic two-nucleon (NN) chiral forces up…
Demonstration of the auxiliary-field Monte Carlo approach for sd-shell nuclei
W. E. Ormand, D. J. Dean, C. W. Johnson +2
We apply the auxiliary-field Monte Carlo approach to the nuclear shell model in the 1s-0d configuration space. The Hamiltonian was chosen to have isovector pairing and isoscalar mu…
Monte Carlo evaluation of path integrals for the nuclear shell model
G. H. Lang, C. W. Johnson, S. E. Koonin +1
We present in detail a formulation of the shell model as a path integral and Monte Carlo techniques for its evaluation. The formulation, which linearizes the two-body interaction b…
Monte Carlo methods for the nuclear shell model
C. W. Johnson, S. E. Koonin, G. H. Lang +1
We present novel Monte Carlo methods for treating the interacting shell model that allow exact calculations much larger than those heretofore possible. The two-body interaction is…
