Topological properties of CP N − 1 models in the large-N limit
Abstract We investigate, by numerical simulations on a lattice, the θ-dependence of 2d CP N − 1 models for a range of N going from 9 to 31, combining imaginary θ and simulated tempering techniques to improve the signal-to-noise ratio and alleviate the critical slowing down of the topological modes....
