Re: [Kwant] Attaching different atom in vacant sublattice

      Hi James,

Yes, this is indeed possible. The first tutorial (
http://kwant-project.org/doc/1/tutorial/tutorial1 )  demonstrates how
to add a single site or a single hopping.

Best regards,

Hello,
I used the tutorial 2.5 for the circular graphene sheet, and in the example,
an atom is deleted at sublattice a at (0,0) via
del sys [a(0,0)]
How can I replace this 'vacancy' with a different atom (with a different
hopping parameter, say, 2)?
Also, from adding this new atom, do I adjust the hopping in sys using
sys[a(-2,1),b(2,2)] = -2 ?

James
