2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/99241We review a novel approach to evaluate the ground-state properties of many-body lattice systems based on an exact probabilistic representation of the dynamics and its long time approximation via a central limit theorem. The choice of the asymptotic density probability used in the calculation is discussed in detail.9 pages, contribution to the proceedings of 12th International Conference on Recent Progress in Many-Body Theories, Santa Fe, New Mexico, August 23-27, 2004Statistical Mechanicstext
