From: The experimental demonstration of a topological current divider
a A topological current divider can be obtained by using multiterminal technology. b The input current \(I\) is asymmetrically partitioned in edge currents \({I}_{a}\) and \({I}_{b}\), with \(I={I}_{a}+{I}_{b}\). An external magnetic field and the back gate control determine the partition ratio \({I}_{a}/{I}_{b}\). The current paths and the device operation can be controlled by changing the magnetic field orientation.
