DESCRIPTION:In chaotic systems it is generally useful only to specify stat
 istical properties of eigenstates\, rather than specific features of a par
 ticular state in an individual system. These properties can often be eluci
 dated by thinking about the dynamics of a wavepacket evolving from a suita
 ble simple initial state. For many-body chaotic systems\, the standard sta
 tistical characterisation is known as the eigenstate thermalisation hypoth
 esis (ETH). It has been clear for a few years\, however\, that ETH is inco
 mplete in the sense that it does not encode correlations that describe the
  dynamics of quantum information in spatially extended systems. I will giv
 e an introduction to this area\, from single-particle examples to ETH. I w
 ill then outline recent work to characterise correlations beyond ETH. \n\n
