Complete wetting is a universnl phenomenon associated with interfaces separ
ating coexisting phases. For example, in the pure gluon theory, at T-c an i
nterface separating two distinct high-temperature deconfined phases splits
into two confined-deconfined interfaces with a complete wetting layer of co
nfined phase between them. In supersymmetric Yang-Mills theory, distinct co
nfined phases may coexist with a Coulomb phase at zero temperature. In that
ease, the Coulomb phase may completely wet a confined-confined interface.
Finally, at the high-temperature phase transition of gluons and gluinos, co
nfined-confined interfaces are completely wet by the deconfined phase, and
similarly, deconfined-deconfined interfaces are completely wet by the confi
ned phase. For these various cases, we determine the interface profiles and
the corresponding complete wetting critical exponents. The exponents depen
d on the range of the interface interactions and agree with those of corres
ponding condensed matter systems. (C) 1998 Elsevier Science B.V. All rights
