Dear Shivang Aragwal,

If the two systems do not contain same sites, then combining them is as simple as syst1.update(syst2) (before finalizing).

Hello All,

I was wondering if there is a way in Kwant to combine two systems. For example, lets say I build two systems sys1 and sys2 (on the kwant.plot graph, the two systems do not overlap, i.e. they are separated by a finite distance). Then, would it be possible to plot the two systems on the same graph, and then calculate transmission of combined sys1+sys2?

Any help would be much appreciated.

Best Regards, Shivang Agarwal
