Dear Sayandip,
As Christoph has said you can adjust a function as hop_color to do so. In
your case just you have to proceed as follow:
*1.select the position of the sites at the edges*
*2.* then make a condition in hop_color or hopping low (transparent ) f*or
the sites at the top (y1=+L) and at the bottom (y2=0 or -L, depending on
your script). *
*To to give you a hint see the following commands,*
### ---------------------
----------------------------------------------------
def hopping_low(site_1, site_2):
x1, y1 =site_1.pos
x2, y2 =site_2.pos
## define the condition for sites that you want to remove hopping
if y2 == L and y1 == -L:
return 0
else:
return 0.2
or
def hopping_color(site_1, site_2):
x1, y1 =site_1.pos
x2, y2 =site_2.pos
## define the condition for sites that you want to remove hopping
if y2 == L and y1 == -L:
return "white"
else:
return "k"
kwant.plot(syst, hop_lw=hopping_low, hop_color=hopping_color,
colorbar=False, ax=ax)
I hope this will help. If not it would be better to give a small script to
your case.
Best
Adel
