Description
We previously applied the mixed phase / capillary wave method to determine the interface tension of the confined-deconfined (CD) phase interface in pure SU(N) gauge theory (N>3) at $T=T_c$. In this work we show how the method can be extended to the study of deconfined-deconfined (DD) interfaces for $T>T_c$, i.e., to measure the interface tension of interfaces between distinct deconfined phases (different $Z_N$-centers). These DD interface tensions depend in general on the $Z_N$-phase shift across the interface and on the temperature $T$. We map out the $T$-dependency of the different DD interface tensions in SU(4) and SU(8) to see whether they show casimir scaling for $T\gg T_c$ and whether there is perfect wetting in the limit $T\to T_c$.
