             Real-time confinement following a quantum
               quench to a non-integrable spin chain


Light cone spreading of correlations and entanglement is a key feature 
of the non-equilibrium dynamics of many-body quantum systems. First 
proposed theoretically, it has been experimentally revealed in cold 
atomic gases and it is expected to be a generic characteristic of any 
quench in a clean system with short range interactions. I will show, 
however, that the phenomenon of dynamical confinement of the elementary 
excitations has dramatic consequences for the non-equilibrium dynamics, 
in particular, the light cone structure gets significantly suppressed. 
Apart from being smoking gun signals of confinement, these effects allow 
for a quantitative study of the spectrum of the system, realizing a kind 
of "quench spectroscopy".
