In general, for arbitrary vectors (formula presented) with (formula presented) the hybridization term can be written as (formula presented) (formula presented) where (formula presented) (formula presented) and (formula presented) (the distance between impurities). If we define (formula presented) we can rewrite (formula presented) and the hybridization is completely characterized by the parameters (formula presented) and (formula presented) so that, in this case, the complete solution of (formula presented) can be obtained for (formula presented) ranging from (formula presented) to (formula presented) For (formula presented) the hybridization term in Eq. (3) is obtained. Note that (formula presented) if (formula presented)
