SUMMARY:The Complex Mesoscale Dynamics of Condensed Matter Systems Unv

DESCRIPTION:Since the end of the past millennium\, high-resolution Ine
 lastic X-Ray Scattering (IXS) has substantially improved our knowledge
  of the collective molecular dynamics of disordered systems.  This tec
 hnique enabled us to explore a host of phenomena occurring over distan
 ce and time windows respectively approaching nearest neighbor atomic s
 eparations and ‘in cage’ oscillation periods. It elucidated fundam
 ental aspects of the high-frequency transport properties of fluids\, s
 uch as the persistence of extended hydrodynamic excitations beyond the
  continuous limit\, the microscopic mechanism driving relaxation pheno
 mena\, and the onset of quantum effects.  In more recent years\, an in
 creasing number of IXS investigations have been focusing on more compl
 ex mesoscale structures promising new functionalities\;  the outcome o
 f these studies could inspire new routes to manipulate the high-freque
 ncy acoustic propagation in materials.  Finally\,  technical improveme
 nts of IXS and other synchrotron-based methods could soon enable a who
 le new class of investigations of transient phenomena in metastable st
 ates or undergoing a phase transition.
