Hi all,
I am working on a lattice which has several sites in one unit cell. Let's denote site index as "i, j ,k", unit cell index as "A, B, C". If I want to see the behavior of some particular site in the unit cell, e.g. S_{A, i}; or some other local information, such as Cross[S_{A, i}, S_{A,j}] \dot S_{A, k}, i,j,k are three given sites in one unit cell, how do I define them?
Thanks, Gang
