Hi! How to attach the leads manually, if I have the coordinates. I use class kwant.builder.Lead and I have an error: "TypeError: Can't instantiate abstract class Lead with abstract methods finalized". What does it mean?
For example, for two atoms: left_lead = kwant.builder.Lead() #add site left_lead[lat(-90.26501, 13.2107)] = 4 left_lead[lat(-91.60269, 12.67463)] = 4 #add hopping left_lead[lat(-90.26501, 13.2107), lat(-91.60269, 12.67463)] = 1 sys.attach_lead(left_lead) С уважением, Татьяна Григоренко grigorenoc...@mail.ru
