Dear Hosein,
You are creating a system with essentially all possible hoppings.
These will take a considerable computational cost regardless of what
you do. Try limiting the number of hoppings to only a few nearest
neighbors per site.
Best,

Dear developers,
I constructed Lat_A and Lat_B for a system.
A1,A2=Lat_A.sublattices
B1,B2=Lat_B.sublattices
I want to set hoppings between Lat_A and Lat_B, and the hoppings are
dependent on the site position.Every atom of Lat_A is coupled to all the
atoms in Lat_B.
Now I have tried it like this :
