DESCRIPTION:This talk will review a number of integrability-based results 
 on the dynamics of quantum spin chains and interacting atomic gases. In eq
 uilibrium\, space- and time-dependent correlations will be reviewed\, toge
 ther with corresponding experimental observations. Integrability will also
  be used to describe the dynamics of (quasi)solitonic excitations and thei
 r scattering properties. For more generic out-of-equilibrium situations\, 
 a number of recent developments will be explained\, including the Quench A
 ction method for explicitly calculating the relaxation of observables afte
 r a quantum quench. The exact solution to the N&eacute\;el-to-XXZ quench u
 sing the QA will be presented\, together with recent results on the necess
 ity to include quasilocal charges in the Generalized Gibbs Ensemble in ord
 er to properly describe post-quench steady-state properties.
