Popis:	We look for domain wall and textured vortex solutions in a two-component Ginzburg–Landau model inspired by two-band superconductivity. The two-dimensional two-component model, with equal coherence lengths and no magnetic field, shows some interesting properties. In the absence of a Josephson type coupling between the two order parameters a “textured vortex” is found by analytical and numerical solution of the Ginzburg–Landau equations. With a Josephson type coupling between the two order parameters we find the system to split up in two domains separated by a domain wall, where the order parameter is depressed to zero.
