Renormalised four-point coupling constant in the three-dimensional O(N) model with N=0
Andrea Pelissetto, Ettore Vicari
We simulate self-avoiding walks on a cubic lattice and determine the second virial coefficient for walks of different lengths. This allows us to determine the critical value of the…
Instability of the O(5) multicritical behavior in the SO(5) theory of high-Tc superconductors
Martin Hasenbusch, Andrea Pelissetto, Ettore Vicari
We study the nature of the multicritical point in the three-dimensional O(3)+O(2) symmetric Landau-Ginzburg-Wilson theory, which describes the competition of two order parameters t…
The critical equation of state of the 2D Ising model
M. Caselle, M. Hasenbusch, A. Pelissetto +1
We compute the 2n-point coupling constants in the high-temperature phase of the 2d Ising model by using transfer-matrix techniques. This provides the first few terms of the expansi…
Lambda-parameter of lattice QCD with the overlap-Dirac operator
C. Alexandrou, H. Panagopoulos, E. Vicari
We compute the ratio between the scale parameter , associated with a lattice formulation of QCD using the overlap-Dirac operator, and of the…
