Abstract

A detailed investigation of the temperature dependence of the spatial string tensionσsinSU(2)gauge theory is presented. A sustained performance of 3 GFLOPS on a 64K Connection Machine CM-2 equivalent has been achieved. Scaling ofσsbetweenβ = 2.5115andβ = 2.74, on large lattices, is demonstrated. Below the critical temperature,Tc,σsremains constant. For temperatures larger than2Tcthe temperature dependence can be parametrized byσs(T) = (0.369 ± 0.014)2g4(T)T2, whereg(T)is a 2-loop running coupling constant with the scale parameter determined asΛT= (0.076 ± 0.013)Tc.
