The external field parallel to the interface, which sets up a steady-state parallel flux, enhances the growth or decay rates of the interfacial modes. More dramatically, asymmetry in the model can introduce an oscillatory component into the interfacial dispersion relation. In certain circumstances, the applied field behaves as a singular perturbation.4 p.application/pdfeng(c) The American Physical Society, 1988Transformacions de fase (Física estadística)Phase transformations (Statistical physics)info:eu-repo/semantics/article14022info:eu-repo/semantics/openAccess
