Abstract: We study 2D wedge wetting using a continuum interfacial Hamiltonian model which is solved by transfer-matrix methods. For arbitrary binding potentials, we are able to exactly calculate the wedge free energy and interface height distribution function and, thus, can completely classify all types of critical behavior. We show that critical filling is characterized by strongly universal fluctuation dominated critical exponents, while complete filling is determined by the geometry rather than fluctuation effects. Related phenomena for interface depinning from defect lines in the bulk are also considered.
