Dear Adel,
Thanks for answering me. I saw the FAQ and I try to reproduce for my case, but
unfortunately didn't work. I changed the lead command:
# Lead a direita (lead 1)
lat_lead1 = kwant.lattice.square(C)
sym_lead1 = kwant.TranslationalSymmetry((-C, 0))
lead1 = kwant.Builder(sym_lead1)
lead1[(lat_lead1(0, 0))] = 0
lead1[lat_lead1(0,0), lat_lead1(1,0)] = -t
syst[(a(0,0), lat_lead1(-1,0))] = -1
syst.attach_lead(lead1)
kwant.plot(syst)
plt.show()

If anyone can help me, i appreciate. Thaks.
