Memory formation in matter is a theme of broad intellectual relevance; it sits at the
interdisciplinary crossroads of physics, biology, chemistry, and computer science. Memory …

Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays
and cementitious pastes to emulsions and physical gels encountered in food or biomedical …

Disordered materials are often out of equilibrium and evolve very slowly in a rugged and
tortuous energy landscape. This slow evolution, referred to as aging, is deemed undesirable …

We show that memory can be encoded in a model amorphous solid subjected to athermal
oscillatory shear deformations, and in an analogous spin model with disordered interactions …

We consider the slow and athermal deformations of amorphous solids and show how the
ensuing sequence of discrete plastic rearrangements can be mapped onto a directed …

Cyclically sheared jammed packings form memories of the shear amplitude at which they
were trained by falling into periodic orbits where each particle returns to the identical …

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 …

A fundamental challenge regarding disordered solids is predicting macroscopic yield—the
point at which elastic behaviour changes to plastic behaviour—from the microscopic …

We show experimentally that both single and multiple mechanical memories can be
encoded in an amorphous bubble raft, a prototypical soft glass, subject to an oscillatory …

We study a model amorphous solid that is subjected to repeated athermal cyclic shear
deformation. It has previously been demonstrated that the memory of the amplitudes of …
