Sum rules regarding the sign problem in Monte Carlo shell model calculations
C. W. Johnson, D. J. Dean
The Monte Carlo shell model is a powerful technique for computational nuclear structure. Only a certain class of nuclear interactions, however, such as pairing and quadrupole, are…
Generalized seniority from random Hamiltonians
C. W. Johnson, G. F. Bertsch, D. J. Dean +1
We investigate the generic pairing properties of shell-model many-body Hamiltonians drawn from ensembles of random two-body matrix elements. Many features of pairing that are commo…
Shape Coexistence and the Effective Nucleon-Nucleon Interaction
P. -G. Reinhard, D. J. Dean, W. Nazarewicz +3
The phenomenon of shape coexistence is discussed within the self-consistent Hartree-Fock method and the nuclear shell model. The occurrence of the coexisting configurations with di…
BB Intermeson Potentials in the Quark Model
T. Barnes, N. Black, D. J. Dean +1
In this paper we derive quark model results for scattering amplitudes and equivalent low energy potentials for heavy meson pairs, in which each meson contains a heavy quark. This "…
Calculation of exciton densities in SMMC
D. J. Dean, S. E. Koonin
We develop a shell-model Monte Carlo (SMMC) method to calculate densities of states with varying exciton (particle-hole) number. We then apply this method to the doubly closed-shel…
