Query: Universal Features of the Excitation Spectrum in Generalized Gibbs
  Distribution Ensemble   It is shown that excitation spectra of Generalized Gibbs Ensembles (GGE) of
one-dimensional integrable models with isotopic symmetry contain universal
features insensitive to details of the distribution. Namely, the low energy
limit of the subsystem of isotopic (for instance, spin) excitations is
described by the effective action of a ferromagnet at thermodynamic equilibrium
with a single temperature and with the stiffness determined by the initial
conditions. The condition of universality is that the entropy per excited
particle is small.
