According to quantum field theory, this sudden snapping to order of electric dipoles, called polarization, generates a secondary electric field that combines with and strengthens the first field.

If you're monitoring the polarization for a logic device or memory element, you can apply a small electric field to traverse this boundary and simultaneously read and write the on-and-off state.

The inversed polarization will disappear under a strong electric field and the single excited state of a polaron will dissociate into a polaron and a bipolaron.
