Abstract [en]

We calculate the nonlinear conductance of a quantum point contact using the nonequilibrium Greens function technique within the Hartree approximation of spinless electrons. We quantitatively reproduce the "0.25 anomaly" in the differential conductance (i. e., the lowest plateau at similar to 0.25-0.3 x 2e(2)/h) as well as an upward bending of higher conductance half-integer plateaus seen in the experiments, and relate these features to the nonlinear screening and pinning effects.
