We consider inhomogeneous current states in low-dimensional systems characterized by spatial separation of phase states with ordered spin and charge degrees of freedom. We show that near the self-duality point in the Ginzburg–Landau spinor model, the inhomogeneity degree of non-Abelian states is higher than that of states with an Abelian distribution of degrees of freedom.
Keywords: strongly correlated system, low-dimensional electron system, inhomogeneous current state, Ginzburg–Landau model, Hopf invariant.
