摘要：

Maximal 't Hooft loops are studied in SO(3) lattice gauge theory at finite-temperature T. Tunneling barriers among twist sectors causing loss of ergodicity for local update algorithms are overcome through parallel tempering, enabling us to measure the vortex free energy F and to identify a deconfinement transition at some beta(crit)(A). The behavior of F below beta(crit)(A) shows however striking differences with what is expected from discretizations in the fundamental representation.
