Abstract

We calculate the energy band structure and the persistent current of two interacting electrons in a quantum ring in the presence of a magnetic flux for a strongly correlated situation: a rotating Wigner molecule with internal vibrations. We discuss a possible bistability and hysteresis in the persistent current in dependence on the magnetic flux.
