摘要：

We study the interface tension alpha-oo of the interface between two ordered domains having different Z(3) values in N(t) = 2 lattice SU(3) gauge theory. A twist in a plane forces the lattice to create the interface dynamically. The tension is computed both by a measurement of free energy differences and as an operator expectation value. For T < T(c), alpha-oo/T3 vanishes, jumps at T = T(c) to a value of about 0.17, and increases monotonically for T > T(c). Near T(c) the unknown corrections to the operator expression arising from finite-volume and non-perturbative beta-function effects are large. The variation of the order parameter <L> and of thermodynamic quantities across the interface is also studied.
