摘要
We investigate partially directed walk models of polymers adsorbed at a surface under the influence of an applied force. The force can be applied at various angles (from perpendicular to parallel to the surface) and the critical force-temperature curves are strongly angle-dependent. We observe some interesting differences between the two-and three-dimensional cases associated with the degeneracy of the ground state in three dimensions.
