Testing Asymptotic Scaling and Nonabelian Symmetry Enhancement

Adrian Patrascioiu, Erhard Seiler

We determine some points on the finite size scaling curve for the correlation length in the two dimensional O(3) and icosahedron spin models. The Monte Carlo data are consistent wi…

Does the XY Model have an integrable continuum limit?

J. Balog, M. Niedermaier, F. Niedermayer +3

The quantum field theory describing the massive O(2) nonlinear sigma-model is investigated through two non-perturbative constructions: The form factor bootstrap based on integrabil…

Percolation and the existence of a soft phase in the classical Heisenberg model

Adrian Patrascioiu, Erhard Seiler

We present the results of a numerical investigation of percolation properties in a version of the classical Heisenberg model. In particular we study the percolation properties of t…

Nontrivial fixed point in nonabelian models

Adrian Patrascioiu, Erhard Seiler

We investigate the percolation properties of equatorial strips in the two-dimensional O(3) nonlinear model. We find convincing evidence that such strips do not percolate at low…

Lattice artefacts and the running of the coupling constant

Adrian Patrascioiu, Erhard Seiler

We study the running of the Lüscher-Weisz-Wolff (LWW) coupling constant in the two dimensional O(3) nonlinear model. To investigate the continuum limit we refine the lattice sp…

Absence of Asymptotic Freedom in Non-Abelian Models

A. Patrascioiu, E. Seiler

The percolation properties of equatorial strips of the two dimensional O(3) nonlinear model are investigated numerically. Convincing evidence is found that a sufficently narrow…
