Dynamical Symmetries in Molecular Electronics

Abstract

Although the analogy between complex quantum dots and molecules as tunneling elements in the single-electron transport devices was recognized even before first CQD were fabricated and investigated, real breakthrough in this field took place after 2000, when both the Coulomb staircase in the current-voltage characteristics and the Kondo-type ZBA anomalies have been found in various molecular systems. The general description of individual molecules and molecular complexes in tunneling devices is given in Section 3.6. Basing on this description of molecular complexes as elements of nanostructures, we concentrate now on the various manifestations of many-particle correlations in specific molecular environments.
