Hello Kwant community, I am considering a 6-terminal sample with 0,1,2,3 the voltage leads and 4,5 the current lead. Normally, with the conductance_matrix M found by kwant I can calculate transport properties (the voltages in vector V) as per the linear equation I = M V, given I = [0,0,0,0,1,-1].
Now I want to plot the current density corresponding to this transport state, but not sure how to do it. For instance, with wf = kwant.wave_function(sys, energy), I can have all scattering wavefunctions wf(4) incoming from the current lead 4. But how to (or is it necessary to) reflect the above current configuration vector I we specified? I presume the current density may vary with different I vectors. Or maybe I misunderstand some basics? Thank you!
