Abstract

Finite size effects in Euclidean Cp(N-1) models with periodic boundary conditions are investigated by means of the 1/N expansion and by Monte Carlo simulations. Analytic and numerical results for the magnetic susceptibility and correlation length are compared and found to agree for small volumes. For large volumes a discrepancy is found and explained as an effect of the physical bound-state extension. The leading-order finite size effects on the Abelian string tension are computed and compared with simulations finding agreement. The finite size dependence of topological quantities is also discussed.
