Figure 2

(Color online) Left: conductance (in units of $G_0$) as a function of the length of the interface $L$ [in units of the magnetic length $l_B=\sqrt{\hslash /\left(e{B}_z\right)}$] for the case of 13 edge channels (filling factor 7) in the ambipolar (thick black line) and generic (red dashed line) cases. Evidently, no plateau in the conductance is reached in either cases. Middle and right: transmission of edge channels number 4 and 13, for which the local-transmission probability in Eq. (2) is, respectively, ${\mathcal{T}}_4=0.87$ and ${\mathcal{T}}_{13}=0.19$, for semiclassical (thick black line) and classical (red dotted line) dynamics. Substantial difference between both behaviors indicates strong influence of interferences between classical trajectories.Reuse & Permissions
