Non-linear WKB Analysis of the String Equation

, 1991
We apply non-linear WKB analysis to the study of the string equation. Even though the solutions obtained with this method are not exact, they approximate extremely well the true solutions, as we explicitly show using numerical simulations.

Self-dual Vortices in the Generalized Abelian Higgs Model with Independent Chern-Simons Interaction

, 1992
Self-dual vortex solutions are studied in detail in the generalized abelian Higgs model with independent Chern-Simons interaction. For special choices of couplings, it reduces to a Maxwell-Higgs model with two scalar fields, a Chern-Simons-Higgs model ...
