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…
Quasi-asymptotic freedom in the two dimensional O(3) model
Adrian Patrascioiu
The behaviour of the renormalized spin 2-point function in the O(3) and dodecahedron spin model are investigated numerically. The Monte Carlo data show excellent agreement between…
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…
The Intrinsic Coupling in Integrable Quantum Field Theories
J. Balog, M. Niedermaier, F. Niedermayer +3
The intrinsic 4-point coupling, defined in terms of a truncated 4-point function at zero momentum, provides a well-established measure for the interaction strength of a QFT. We sho…
