Hello! I have a question about the conductance formula that you have given in Kwant paper.It reads as summation over elctrodes of the scattering matrix.My question is about how the calculation are being done in different regimes as transmission formula gets changed in different regimes.In diffusive regime its no of modes multiplied lambda/l+lambda i.e.(M*l/L+l).How kwant deals with it?And also what about the (-del F/del E ) i.e differene in energy levels in both the leads(say we have only 2).My apology if it's more of a physics question,but I want to calculate with hands.Any intuition is appreciated.
