A new approach to significantly reduce the negative sign problem in quantum Monte Carlo

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/147821We present a new approach for Monte Carlo simulations of lattice quantum spin systems which is able to eliminate the negative sign problem. Its complexity is linear in the volume of the lattice. Its efficiency is tested on a simple 2-dimensional fermionic model.Improved version of the algorithm, 6 pages of LaTexHigh Energy Physics - LatticeCondensed MatterA new approach to significantly reduce the negative sign problem in quantum Monte Carlotext
