DESCRIPTION:Speaker: Martin van Hecke\nhosted by Scott Waitukaitis\nAbstrac
 t: Memory effects probe the complexity of disordered matter and its fundam
 ental constituents and interactions. While models based on independent ele
 ments capture generic memories\, interactions are predicted to produce man
 y interaction-induced memories which so far have been observed in artifici
 al systems only. Here we reveal that archetypical disordered materials - p
 olycrystalline alloys\, crumpled sheets\, and steel wool - store multiple 
 memories that strengthen with repeated cycling - in stark contrast to pred
 ictions for non-interacting systems. Interacting-based models capture our 
 observations and predict a cascade of interaction-induced memory motifs\, 
 including the dominant one observed here. Our results reveal hitherto hidd
 en complexity in disordered media\, opening a fresh route towards the obse
 rvation\, modeling and utilization of interaction-induced memories\, inclu
 ding for in-materia computing.
