22nd order high-temperature expansion of nearest-neighbor models with O(2) symmetry on a simple cubic lattice
Massimo Campostrini, Martin Hasenbusch, Andrea Pelissetto +1
We present the high-temperature series for a nearest-neighbor model with O(2) symmetry on a simple cubic lattice with the most general single-site potential. In particular, the mag…

3D Ising Model with Improved Scaling Behaviour
M. Hasenbusch, K. Pinn, S. Vinti
We present results from the simulation of a two-coupling spin-1 model with states 0,+1,-1 and nearest neighbour interaction. By a suitable choice of couplings we are able to drasti…
