DESCRIPTION:Light cone spreading of correlations after a quantum quench is
  a key  phenomenon characterising integrable models\, which has also been 
 measured in  cold atomic experiments. Guided by numerical results for the 
 Ising chain\, we&#39\;ll  show that when integrability is broken in such a
  way that the spectrum consists  of only bound states\, correlations at la
 rge distance get frozen soon after the  quench as a consequence of the con
 finement of the elemetary excitations\,  implying a breakdown of the light
 -cone scenario.
