Abstract
We review results obtained using Shell-Model Monte Carlo (SMMC) techni ques. These methods reduce the imaginary-time many-body evolution oper ator to a coherent superposition of one-body evolutions in fluctuating one-body fields; the resultant path integral is evaluated stochastica lly. After a brief review of the methods, we discuss a variety of nucl ear-physics applications. These include studies of the ground-state pr operties of pf-shell nuclei, Gamow-Teller strength distributions, ther mal and rotational pairing properties of nuclei near N = Z, gamma-soft nuclei, and beta beta-decay in Ge-76. Several other illustrative calc ulations are also reviewed. Finally, we discuss prospects for further progress in SMMC and related calculations.
