Multiple transient memories in sheared suspensions: robustness, structure, and routes to plasticity.

Multiple transient memories, originally discovered in charge-density-wave conductors, are a remarkable and initially counterintuitive example of how a system can store information about its driving. In this class of memories, a system can learn multiple driving inputs, nearly all of which are eventually forgotten despite their continual input. If sufficient noise is present, the system regains ...

Multiple transient memories in experiments on sheared non-Brownian suspensions.

A system with multiple transient memories can remember a set of inputs but subsequently forgets almost all of them, even as they are continually applied. If noise is added, the system can store all memories indefinitely. The phenomenon has recently been predicted for cyclically sheared non-Brownian suspensions. Here we present experiments on such suspensions, finding behavior consistent with mu...

Abstract Submitted for the MAR13 Meeting of The American Physical Society Transient Memories in Experiments on Sheared Non-Brownian Suspensions

Submitted for the MAR13 Meeting of The American Physical Society Transient Memories in Experiments on Sheared Non-Brownian Suspensions JOSEPH PAULSEN, SIDNEY NAGEL, University of Chicago — A novel kind of memory has been observed in simulations of cyclically sheared nonBrownian suspensions [1]. Here we report on experiments designed to see these effects in the lab. In this type of memory, a sys...

Dynamic structure factor study of diffusion in strongly sheared suspensions

Diffusion of neutrally buoyant spherical particles in concentrated monodisperse suspensions under simple shear flow is investigated. We consider the case of nonBrownian particles in Stokes flow, which corresponds to the limits of infinite Péclet number and zero Reynolds number. Using an approach based upon ideas of dynamic light scattering we compute selfand gradient diffusion coefficients in t...

Self-diffusion in sheared suspensions

Self-diffusion in a suspension of spherical particles in steady linear shear flow is investigated by following the time evolution of the correlation of number density fluctuations. Expressions are presented for the evaluation of the self-diffusivity in a suspension which is either macroscopically quiescent or in linear flow at arbitrary Peclet number Pe = j a 2 / 2 D , where j i s the shear rat...
