Dear Sir, I am using Kwant for 2 months. I've studied the conductance behaviour in a square lattice for two terminal case. But for the 4 terminal case I've some confusion about the hall conductance. I've read your post about the hall resistance. You wrote there,
nonlocal_resistance = np.linalg.solve(cm, [1, 0, -1])[1] Why did you put the currents I_0=1, I_1=0 and I_2=-1? Also can you please tell me how do I calculate the longitudinal conductance for the 4 terminal case.
