Figure 2. Topological characterization of the 4-terminal junction for the single-channel case.

Figure 2

(a) Position of the four Weyl points in the space of ϕ1,2,3 of the single-channel 4-terminal junction, the colour code indicating the respective charge. (b) The resulting transconductance G12 indicating the Chern number, as a function of ϕ3 for the same single-channel junction as in a.
