We will discuss a recent result on dynamical localization for a simple, disordered many-body system. For the xy-spin chain with a disordered transversal magnetic field, we prove dynamical localization. This is expressed in terms of a zero-velocity Lieb-Robinson bound which holds on (disorder) average. This is joint work with Gunter Stolz (from the University of Alabama at Birmingham) and Eman Hamza (from Cairo University in Egypt).
