A general formalism for the study of excitations above equilibrium in Betheansatz solvable models is presented. Nonzero temperature expressions fordressed energy, momentum, spin and charge are obtained, and it is found thatthe dressed spin and charge are in general momentum dependent. For anelectronic model one may only have spin-charge separation at zero temperaturewhere the ground state is half-filled and has zero magnetisation. Finally, theexcitations of the Hubbard-Shastry models are examined in detail.
