Hi,
I am using the honeycomb lattice and boson hubbard model from the alps library on vispython. I wish to measure the staggered structure factor given by the equation
S = 1/N * Summation [ e(i)e(j) <n(i)n(j)> ]
where e(i) = 1 or -1 for i on sublattice A(B) in terms of density-density correlations. I know that alps measure the density structure factor using wave vectors. How can i make alps measure the structure factor given above ?
Regards, Mike
Which code are you using?

I need to know which ALPS code you are using, not which programming language.

What program are you using to measure these quantities?

The observable "Checkerboard Charge Order" is what you want to look at.
