Cluster Percolation and Chiral Phase Transition
arXiv:hep-lat/0206030 · doi:10.1103/PhysRevD.66.037502 10.1103/PhysRevD.72.029901
Abstract
The Meron Cluster algorithm solves the sign problem in a class of interacting fermion lattice models with a chiral phase transition. Within this framework, we study the geometrical features of the clusters built by the algorithm, that suggest the occurrence of a generalized percolating phase transition at the chiral critical temperature in close analogy with Fortuin-Kasteleyn percolation in spin models.
