Possible Failure of Asymptotic Freedom in Two-Dimensional and -Models
S. Caracciolo, R. G. Edwards, A. Pelissetto +1
We have simulated the two-dimensional and -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…
Wolff-Type Embedding Algorithms for General Nonlinear -Models
Sergio Caracciolo, Robert G. Edwards, Andrea Pelissetto +1
We study a class of Monte Carlo algorithms for the nonlinear -model, based on a Wolff-type embedding of Ising spins into the target manifold . We argue heuristically that, at…
Dynamic Critical Behaviour of Wolff's Algorithm for -Models
S. Caracciolo, R. G. Edwards, A. Pelissetto +1
We study the performance of a Wolff-type embedding algorithm for -models. We find that the algorithm in which we update the embedded Ising model à la Swendsen-Wang has cr…
