$θ$ -dependence in the small- $N$ limit of $2 d$ $C P^{N - 1}$ models

Mario Berni, Claudio Bonanno, Massimo D'Elia

We present a systematic numerical study of $θ$ -dependence around $θ = 0$ in the small- $N$ limit of $2 d$ $C P^{N - 1}$ models, aimed at clarifying the possible presence of a divergent to…

Large- $N$ expansion and $θ$ -dependence of $2 d$ $C P^{N - 1}$ models beyond the leading order

Mario Berni, Claudio Bonanno, Massimo D'Elia

We investigate the $θ$ -dependence of 2-dimensional $C P^{N - 1}$ models in the large- $N$ limit by lattice simulations. Thanks to a recent algorithm proposed by M. Hasenbusch to improv…
