Query: How to experimentally detect a GGE? - Universal Spectroscopic Signatures
  of the GGE in the Tonks gas   In this work we study the properties of the density density correlation
function of the 1-D Lieb-Liniger model with infinite repulsion in the GGE
regime. The GGE describes the equilibrated system in the long time limit after
a quench from a generic initial state. In the case that the initial and hence
the final state has low entropy per particle we find that the density density
correlation function has a universal form, in particular it depends on a few
parameters corresponding to "key" momenta and has power law dependence on the
distance. This provides an experimental signature of the GGE which may readily
be identified through spectroscopy. These signatures are universal and robust
to initial sate preparation.
