Abstract:
A detailed investigation of the temperature dependence of the spatial string tension in SU(2) gauge theory, performed on Connection Machines CM-2, is presented. A sustained performance of 3 GFLOPS on a 64K CM-2 equivalent is achieved. For the first time, scaling of the spatial string tension is demonstrated. Thus, it persists in the continuum limit. Below the critical temperature no temperature dependance is observed. For temperatures larger than two times the critical temperature the scaling behavior can be parameterized by \sqrt{\sigma_s(T)} = (0.369 +/- 0.014)g~2(T)T, where g(T) is a 2-loop running coupling constant with the scale parameter determined as \Lambda_T = (0.076 +/- 0.013)T_c.- talk: Juelich 1993/06/14
