Description

Conductance in a quantum wire: effect of equilibration

Tobias Micklitz (Universidade Livre de Berlim - Alemanha)


We study the effect of equilibration on linear and nonlinear conductances of spinless fermions in clean quantum wires. Equilibration of electrons in clean quantum wires is a very slow process since relevant scattering processes involve the band bottom. Large effects, therefore, only can be expected close to the conductance plateau transition where temperature is of the order of the band width. Close to the quantum phase transition where the conductance jumps from zero to one conductance quantum the conductance obtains an universal form governed by the ratios of temperature, bias voltage and gate voltage.
