Understand

The standard view is that at low energies Mott insulators exhibit only magnetic properties while charge degrees of freedom are frozen out as the electrons become localized by a strong Coulomb repulsion.

We demonstrate that this is in general not true: for certain spin textures {\it spontaneous circular electric currents} or {\it nonuniform charge distribution} exist in the ground state of Mott insulators.
In addition, low-energy ``magnetic'' states contribute comparably to the dielectric and magnetic functions $\epsilon_{ik}(\omega)$ and $\mu_{ik}(\omega)$ leading to interesting phenomena such as rotation the electric field polarization and resonances which may be common for both functions producing a negative refraction index in a window of frequencies.

Bogoliubov came very close to this result long ago, by using a perturbative approach with respect to the small parameter t / U t/U to describe the correlated metallic state. N. N. Bogolyubov, Lectures on Quantum Statistics, Gordon and Breach, New York, p. 120 (1967)
