FINITE-SIZE ANALYSIS OF THE PSEUDO SPECIFIC-HEAT IN SU(2) GAUGE-THEORY

We investigate the pseudo specific heat of SU(2) gauge theory near the crossover point on 4(4) to 16(4) lattices. Several different methods are used to determine the specific heat. The curious finite size depen dence of the peak maximum is explained from the interplay of the cross over phenomenon with the deconfinement transition occurring due to the finite extension of the lattice. In this context we calculate the mod ulus of the lattice average of the Polyakov loop on symmetric lattices and compare it to predictions from a random walk model.
