Hello, I want to create a three-wire "(1D each wire) junction for calculating conductance. Can I use kwant.lattice.chain() to use three separate chains and then join them somehow? I also need to change the angle between these 3 wires. It would be really helpful if anyone can give me the idea to make such a graph (lattice ) in kwant. Thanks, Sayandip Dhara
Hello Sayandip, It would be easier to create some 2D lattice and embed the 1D wires as stripes of unit thickness, all parallel and in the same direction (say x ), with y-coordinate being 0,1,2 for the three leads. Then, create a three-site system at (0,0), (0,1), (0,2) and attach leads to it. The hoppings set up between these 3 sites will model your junction transmissions. Best wishes, Sergey
