Universal amplitude ratios in the 2D four state Potts model
Michele Caselle, Roberto Tateo, Stefano Vinti
We present a Monte Carlo study of various universal amplitude ratios of the two dimensional q=4 Potts model. We simulated the model close to criticality in both phases taking care…
On the phase diagram of the discrete spin models
Patrick Dorey, Paolo Provero, Roberto Tateo +1
We point out some problems with the previously-proposed phase diagram of the spin models. Consideration of the diagram near to the decoupling surface using both exact and app…
Critical Exponents of the 3D Ising Universality Class From Finite Size Scaling With Standard and Improved Actions
M. Hasenbusch, K. Pinn, S. Vinti
We propose a method to obtain an improved Hamiltonian (action) for the Ising universality class in three dimensions. The improved Hamiltonian has suppressed leading corrections to…
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…
Block Spin Effective Action for Polyakov Loops in 4D SU(2) LGT
K. Pinn, S. Vinti
Using a variant of the IMCRG method of Gupta and Cordery, we explicitly compute majority rule block spin effective actions for the signs of the Polyakov loops in 4D SU(2) finite te…
Nature of the Vacuum inside the Color Flux Tube
Ferdinando Gliozzi, Stefano Vinti
The interior of the color flux tube joining a quark pair can be probed by evaluating the correlator of pair of Polyakov loops in a vacuum modified by another Polyakov pair, in orde…
