Abstract

In this paper we predict many interesting new properties of vortices in highly anisotropic density wave systems subject to strong transverse electric fields. We mainly concentrate on ground state properties. Besides electric field-induced vortices we consider also thermally activated vortices. A new type of temperature-driven transition between two different phases of density waves in strong fields is predicted and several new properties of those phases are reported.
