โœฆ Synopsis

An electron transport through a quantum wire with a constriction is studied in the framework of a microscopic approach. We find two qualitatively different types of behaviour depending on the strength of the barrier at the constriction. For high barriers the DC conductance tends to zero with decrease of temperature, whereas for low barriers it remains finite. We associate this result with the different character of electromagnetic excitations created by electrons propagating through the system in these two cases.

Within the framework of the Feynman variational method the bipolaron binding energy and the bipolaron effective mass in cylindrical and planar quantum wires with 'parabolic' confinement are calculated. An analogy is found between the effects due to strong confinement and those due to the application
