Lattice gauge theories in the strong coupling and static limits as a sign-problem-free Ising model

Abstract

The effective action of the SU(N) Polyakov loop model in the strong coupling region and in the static limit for the quark determinant can be mapped onto the Ising model in any dimensions, with the Ising variables attached on the links of the lattice. We use this reformulation to study the finite temperature SU(2) lattice gauge theory at finite baryon density.
