<span>Cyclic Memories in Disordered Materials<br>
</span>
<div><br>
</div>
<span>Cyclic driving happens all around us. Buildings and bridges are repeatedly loaded and unloaded, and many organisms synchronize their functions with day and night. In some cases, a material that is deformed repeatedly can "learn" and recall the amplitudes
of that driving, effectively adding a programmable component to its future response. I present experiments with a suspension of particles in liquid, and a disordered solid made of closely packed particles. These materials exemplify two different but generic
ways that non-equilibrium matter can retain memories, with each one having parallels in another, seemingly disparate system. Studying memory formation can thus illuminate a material’s non-equilibrium nature, including the importance of disorder and noise for
learning.</span><br>
