Dear ALPS community, I am looking to simulate something with a few quantum degrees of freedom beyond those which live on the lattice. For concreteness, imagine a spin at each lattice site that can couple to a single photon mode that permeates the whole lattice, similar to the Dicke model. Naively there would seem to be no fundamental obstacle to simulating this, so I wonder if there is a natural way to do it within ALPS, or if I should be looking for a clever hack. Thank you for any help, Alex Edelman
