The reduced tension σ cd of the interface between the confined and the deconfined phase of SU (3) pure gauge theory is determined from numerical simulations of the first transfer matrix eigenvalues. At Tc = 1/Lt we find σ cd = 0.139(4)T 2 c for Lt = 2. The interfaces show universal behavior because the deconfined-deconfined interfaces are completely wet by… (More)

We present a numerical determination of the order-disorder interface tension, σ od , for the two-dimensional seven-state Potts model. We find σ od = 0.0114 ± 0.0012, in good agreement with expectations based on the conjecture of perfect wetting. We take into account systematic effects on the technique of our choice: the histogram method. Our measurements… (More)

We present results for the confinement-deconfinement interface tension σ cd of quenched QCD. They were obtained by applying Binder's histogram method to lattices of size L 2 × L z × L t for L t = 2 and L = 8, 10, 12 and 14 and various L z ∈ [L, 4 L]. The use of a multicanonical algorithm and rectangular geometries have turned out to be crucial for the… (More)

The reduced tension σ cd of the interface between the confined and the deconfined phase of SU(3) pure gauge theory is related to the finite size effects of the first transfer matrix eigenvalues. A lattice simulation of the transfer matrix spectrum at the critical temperature T c = 1/L t yields σ cd = 0.139(4)T 2 c for L t = 2. We found numerical evidence… (More)

We present a multicanonical algorithm for the SU(3) pure gauge theory at the deconfinement phase transition. We measure the tunneling times for lattices of size L 3 ×2 for L = 8, 10, and 12. In contrast to the canonical algorithm the tunneling time increases only moderately with L. Finally, we determine the interfacial free energy applying the… (More)

We present results for the confinement-deconfinement interface tension α cd of quenched QCD. They were obtained by applying Binder's histogram method to lattices of size L 2 ×Lz ×Lt for Lt = 2 and L = 8, 10, 12 and 14 with Lz = 30 for L = 8 and Lz = 3L otherwise. The use of a multicanonical algorithm and cylindrical geometries have turned out to be crucial… (More)
