How to assign different hopping parameter 't' to different sites

How do I assign different values hopping parameter 't' for different sites for fermionic hubbard model.
For a 12 site chain, I tried to multiply
and assign different values of
For a 12 site chain, I tried to multiply
model.lat.unit_cell = model.lat.unit_cell*12
and assign different values of
t(i) (i = 1, 12)
to each of the element of unit cell. But that is not matching with exact diagonalization results.
