| Abstract: | A model consisting of an array of flexible self-avoiding domain walls extending across a two-dimensional medium is considered. Adsorption phenomena in the presence of edgepinning forces and rupture, segregation, and order-disorder transitions due to shortrange attractive and repulsive interactions between the domain walls are studied using fermion transfer-matrix methods.Heisenberg Fellow of the Deutsche Forschungsgemeinschaft |
