Query: External field induced switching of tunneling current in the coupled
  quantum dots   We investigated the tunneling current peculiarities in the system of two
coupled by means of the external field quantum dots (QDs) weakly connected to
the electrodes in the presence of Coulomb correlations. It was found that
tuning of the external field frequency induces fast multiple tunneling current
switching and leads to the negative tunneling conductivity. Special role of
multi-electrons states was demonstrated. Moreover we revealed conditions for
bistable behavior of the tunneling current in the coupled QDs with Coulomb
correlations.
