Findings

Evidence for a finite temperature deconfinement transition.

Transition driven by U(1) magnetic charge condensation.

Critical exponents consistent with the 3D Ising model.

Abstract

We study the SO(3) lattice gauge theory in 3+1 dimensions with the adjoint Wilson action modified by a $\mathbb{Z}_2$ monopole suppression term and by means of the Pisa disorder operator. We find evidence for a finite temperature deconfinement transition driven by the condensation of U(1) magnetic charges. A finite-size scaling test shows consistency with the critical exponents of the 3D Ising model.
