| * ABSTRACT | |||||||
| Interacting electrons in solids form weak superstructures like charge- and spin- density waves, Wigner crystals, etc. The resulting symmetry broken states give rise to a rich complex of nonlinear and nonstationary phenomena, showing various topological defects like vortices (dislocations), phase slips, and solitons. A numeric modeling of transient processes in nano-junctions allows us to observe a turbulent initial dynamics which relaxes to a stationary vortex state. A more microscopic revision of the intuitive Ginzburg-Landau theory was required to treat correctly the conservation of condensed electrons at presence of moving vortex cores. The new equations have been derived efficiently with the help of the chiral transformation, paying attention at the emerging chiral anomaly. The new earlier unknown non-analytical form of equations brings challenging complications to the numerical procedure. | |||||||
