Surface phases and surface phase transitions: A renormalization-group calculation
… and three dimensions. We show how position-space renormalization group methods, previously used in homogeneous bulk calculations, can be generalized to give surface properties. In two dimensions a 4x4 cell-cluster approximation gives critical and thermodynamic properties in quantitative agreement …

Model for the onset of nonlinear flow dissipation in 2D superfluid helium films
… and Siggia to include to flow velocity. The renormalization group calculation is carried out on a computer to determine the dissipation as a function of superfluid velocity. We find the onset of nonlinear dissipation is driven by two mechanisms whose relative contributions are temperature …

Studies in random Ising spin systems
… of random bonds or random fields. Specific calculations are done on the twodimensional short-ranged random-bond model and the three-dimensional random-field model. The phenomenological renormalization group and the transfer-matrix method are generalized to random systems and applied to the …
