The Effects of Next-Nearest-Neighbor Interactions on the Orientation Dependence of Step Stiffness: Reconciling Theory with Experiment for Cu(001)
T. J. Stasevich, T. L. Einstein, R. K. P. Zia +3
Within the solid-on-solid (SOS) approximation, we carry out a calculation of the orientational dependence of the step stiffness on a square lattice with nearest and next-nearest ne…

Two-dimensional Dilute Ising Models: Defect Lines and the Universality of the Critical Exponent ν
Ferenc Szalma, Ferenc Igloi
We consider two-dimensional Ising models with randomly distributed ferromagnetic bonds and study the local critical behavior at defect lines by extensive Monte Carlo simulations. B…
