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…
Discrete Symmetry Enhancement in Nonabelian Models and the Existence of Asymptotic Freedom
A. Patrascioiu, E. Seiler
We study the universality between a discrete spin model with icosahedral symmetry and the O(3) model in two dimensions. For this purpose we study numerically the renormalized two-p…
Comment on "Percolation Properties of the 2D Heisenberg Model"
Adrian Patrascioiu, Erhard Seiler
We comment on a recent paper by Allès et al.
Comment on "Scaling Hypothesis for the Spectral Densities in the Nonlinear Sigma Model"
A. Patrascioiu, E. Seiler
We comment on the recent paper by Balog and Niedermaier [hep-th/9701156].
Comment on `Asymptotic Scaling in the Two-Dimensional O(3) sigma-Model at Correlation Length 10^5' by S. Caracciolo et al
A. Patrascioiu, E. Seiler
We explain why in our view an extrapolation from small lattices containing only perturbative information cannot be sufficient to determine nonperturbative qunatities and therefore…
Super-Instantons and the Reliability of Perturbation Theory in Non-Abelian Models
A. Patrascioiu, E. Seiler
In dimension the low temperature behavior of systems enjoying a continuous symmetry is dominated by super-instantons: classical configurations of arbitrarily low energy.…
