Shell Model Monte Carlo method in the -formalism and applications to the Zr and Mo isotopes
C. Ozen, D. J. Dean
We report on the development of a new shell-model Monte Carlo algorithm which uses the proton-neutron formalism. Shell model Monte Carlo methods, within the isospin formulation, ha…
Shell Model Monte Carlo Investigation of Rare Earth Nuclei
J. A. White, S. E. Koonin, D. J. Dean
We utilize the Shell Model Monte Carlo (SMMC) method to study the structure of rare earth nuclei. This work demonstrates the first systematic ``full oscillator shell plus intruder'…
SMMC method for two-neutrino double beta decay
P. B. Radha, D. J. Dean, S. E. Koonin +5
Shell Model Monte Carlo (SMMC) techniques are used to calculate two-neutrino double beta decay matrix elements. We validate the approach against direct diagonalization for C…
Shell Model Monte Carlo Studies of -Soft Nuclei
Y. Alhassid, G. F. Bertsch, D. J. Dean +1
We present Shell Model Monte Carlo calculations for nuclei within the full major shell 50-82 for both protons and neutrons. The interaction is determined solely by self-consistency…
Thermal properties of Fe-54
D. J. Dean, S. E. Koonin, K. Langanke +2
We study the thermal properties of Fe-54 with the Brown-Richter interaction in the complete 1p0f model space. Monte Carlo calculations show a peak in the heat capacity and rapid in…
Practical solution to the Monte Carlo sign problem: Realistic calculations of 54Fe
Y. Alhassid, D. J. Dean, S. E. Koonin +2
We present a practical solution to the "sign problem" in the auxiliary field Monte Carlo approach to the nuclear shell model. The method is based on extrapolation from a continuous…
