A new approach to perform numerical simulations of systems with a $\theta$-vacuum term is proposed, tested, and applied to CP^3. The main new ingredient of this approach is the method used to compute the probability distribution function of the topological charge at $\theta$ = 0. We comment also on the possibility of applying this approach to QCD at finite baryon density.

Abstract
A new approach to perform numerical simulations of systems with a $\theta$-vacuum term is proposed, tested, and applied to CP^3. The main new ingredient of this approach is the method used to compute the probability distribution function of the topological charge at $\theta$ = 0. We comment also on the possibility of applying this approach to QCD at finite baryon density.File in questo prodotto:
