BOUND STATES OF TOPOLOGICAL DEFECTS IN THE SYSTEM OF NON-LINEAR COUPLED GINZBURG-LANDAU EQUATIONS

Bound states of topological defects arising in a tetragonal lattice formed by two orthogonal standing parametrically excited capillary surface waves are investigated. A system of four coupled Ginzburg-Landau equations is proposed to model the bound states. Numerical modeling of this system gave solutions corresponding to the bound states observed in experiment.
