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…

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…

Existence of Algebraic Decay in Nonabelian Ferromagnets
A. Patrascioiu
The low temperature regime of nonabelian two-dimensional ferromagnets is investigated. The method involves mapping such models into certain site-bond peroclation processes and usin…
