Thermodynamical limit of general gl(N) spin chains II: Excited states and energies
We consider the thermodynamical limit of a gl(N) spin chain with arbitrary
representation at each site of the chain. We consider excitations (with holes
and new strings) above the vacuum and compute their corrections in 1/L to the
densities and the energy.Comment: 29 pages misprints in the example of sect 5.1 amended and a mistake
