Percolation and Deconfinement in SU(2) Gauge Theory
S. Fortunato
Cluster percolation and second order thermal phase transitions show an amazing number of common features: power laws of the variables at criticality, scaling relations of the criti…
Effective Z(2) Spin Models of Deconfinement and Percolation in SU(2) Gauge Theory
S. Fortunato, F. Karsch, P. Petreczky +1
Effective theories are helpful tools to gain an intuitive insight into phenomena governed by complex laws. In this work we show by means of Monte Carlo simulations that Z(2) spin m…
Percolation and Critical Behaviour in SU(2) Gauge Theory
S. Fortunato, F. Karsch, P. Petreczky +1
The paramagnetic-ferromagnetic transition in the Ising model can be described as percolation of suitably defined clusters. We have tried to extend such picture to the confinement-d…
Percolation and Deconfinement in SU(2) Gauge Theory
Santo Fortunato, Helmut Satz
The deconfinement transition in SU(2) gauge theory and the magnetization transition in the Ising model belong to the same universality class. The critical behaviour of the Ising mo…
Cluster Percolation in O(n) Spin Models
P. Blanchard, S. Digal, S. Fortunato +3
The spontaneous symmetry breaking in the Ising model can be equivalently described in terms of percolation of Wolff clusters. In O(n) spin models similar clusters can be built in a…
Percolation and Magnetization for Generalized Continuous Spin Models
S. Fortunato, H. Satz
For the Ising model, the spin magnetization transition is equivalent to the percolation transition of Fortuin-Kasteleyn clusters; this result remains valid also for the conventiona…
Percolation and Magnetization in the Continuous Spin Ising Model
Piotr Bialas, Philippe Blanchard, Santo Fortunato +2
In the strong coupling limit the partition function of SU(2) gauge theory can be reduced to that of the continuous spin Ising model with nearest neighbour pair-interactions. The ra…
