We investigate the transport properties of a multi-level quantum dot with strong electron–electron interaction by the use of the equivalent single-particle multi-channel network and Landauer formulae. By including the effect of cotunneling to the leads the calculated results show Kondo-type transport in valleys of conductance as a function of the gate voltage which was found in recent experiments. We calculate the Kondo temperature for various parameters. We discuss the condition for observing this effect in the experiments.

Parabolic Quantum Dot

The ground-state energy of polaron was obtained with strong electron-LO-phonon coupling by using a variational method of the Pekar type in a parabolic quantum dot (QD). Quantum transition occurs in the quantum system due to the electron-phonon interaction and the influence of temperature. That is the polaron transition from the ground-state to the first-excited state after absorbing a LO-phonon and it causes the changing of the polaron lifetime. Numerical calculations are performed and the results illustrate the relations of the ground-state lifetime of the polaron on the ground-state energy of polaron, the electric field strength, the temperature, the electron-LO-phonon coupling strength and the confinement length of the quantum dot.
