Hi,
OK, I believe I may in fact already have found an answer at the end of http://alps.comp-phys.org/mediawiki/index.php/Tutorials:Parameters ... that will also work with models that I define myself, as long as I define them on translationally symmetric lattices?
cheers, Johannes

Hi all,
I would like to use exact diagonalization to calculate the first few energy levels of a quantum spin chain, but as a function of quasi-momentum, i.e. the eigenvalue of the translation operator that shifts the lattice by one site. Is there any simple way to accomplish such a thing using ALPS?
Thank you very much in advance, Johannes
