Query: Luttinger liquid universality in the time evolution after an interaction
  quench   We provide strong evidence that the relaxation dynamics of one-dimensional,
metallic Fermi systems resulting out of an abrupt amplitude change of the
two-particle interaction has aspects which are universal in the Luttinger
liquid sense: The leading long-time behavior of certain observables is
described by universal functions of the equilibrium Luttinger liquid parameter
and the renormalized velocity. We analytically derive those functions for the
Tomonaga-Luttinger model and verify our hypothesis of universality by
considering spinless lattice fermions within the framework of the density
matrix renormalization group.
