Possible Failure of Asymptotic Freedom in Two-Dimensional $R P^{2}$ and $R P^{3}$ $σ$ -Models

S. Caracciolo, R. G. Edwards, A. Pelissetto +1

We have simulated the two-dimensional $R P^{2}$ and $R P^{3}$ $σ$ -models, at correlation lengths up to about 220 (resp.\ 30), using a Wolff-type embedding algorithm. We see no evidence o…

Random Walks with Long-Range Self-Repulsion on Proper Time

S. Caracciolo, G. Parisi, A. Pelissetto

We introduce a model of self-repelling random walks where the short-range interaction between two elements of the chain decreases as a power of the difference in proper time. Analy…

Topological susceptibility and string tension in CP(N-1) models

Massimo Campostrini, Paolo Rossi, Ettore Vicari

We investigate the features of $CP^{N - 1}$ models concerning confinement and topology. In order to study the approach to the large- $N$ asymptotic regime, we determine the topo…

$1/ N$ Expansion of Two-Dimensional Models in the Scaling Region

Massimo Campostrini, Paolo Rossi

The main technical and conceptual features of the lattice $1/ N$ expansion in the scaling region are discussed in the context of a two-parameter two-dimensional spin model interpola…

Scaling and asymptotic scaling in two-dimensional $C P^{N - 1}$ models

Massimo Campostrini, Paolo Rossi, Ettore Vicari

Two-dimensional $C P^{N - 1}$ models are investigated by Monte Carlo methods on the lattice, for values of $N$ ranging from 2 to 21. Scaling and rotation invariance are studied by com…

Monte Carlo simulation of lattice $CP^{N - 1}$ models at large N

Ettore Vicari

In order to check the validity and the range of applicability of the 1/N expansion, we performed numerical simulations of the two-dimensional lattice CP(N-1) models at large N, in…

Topological susceptibility and string tension in the lattice CP(N) models

M. Campostrini, P. Rossi, E. Vicari

In the lattice CP(N) models we studied the problems related to the measure of the topological susceptibility and the string tension . We perfomed numerical simulations at N=4 and N…

Wolff-Type Embedding Algorithms for General Nonlinear $σ$ -Models

Sergio Caracciolo, Robert G. Edwards, Andrea Pelissetto +1

We study a class of Monte Carlo algorithms for the nonlinear $σ$ -model, based on a Wolff-type embedding of Ising spins into the target manifold $M$ . We argue heuristically that, at…
