Flag manifold sigma models from SU(n) chains
One dimensional SU(n) chains with the same irreducible representation R at each site are considered. We determine which R admit low-energy mappings to a SU(n)/[U(1)]n−1 flag manifold sigma model, and calculate the topological angles for such theories. Generically, these models will have fields with...
