Critical properties of the Z(3) interface in (2+1)-D SU (3) gauge theory Original Research Article

We study the interface between two different Z(3) vacua in the deconfined phase of SU(3) pure gauge theory in 2 + 1 dimensions just above the critical temperature. In simulations of the Euclidean lattice gauge theory formulation of the system we measure the fluctuations of the interface as the critical temperature is approached and as a function of system size. We show that the intrinsic width of the interface remains small even very close to the critical temperature. Some dynamical exponents which govern the interaction of the interface with our Monte Carlo algorithm are also estimated. We conclude that the Z(3) interface has properties broadly similar to those in many other comparable statistical mechanical systems.
