We consider two schematic models of glasses subjected to oscillatory shear deformation, motivated by the observations, in computer simulations of a model glass, of a nonequilibrium transition from a localized to a diffusive regime as the shear amplitude is increased, and of persistent memory effects in the localized regime. The first of these schematic models is the NK model, a spin model with disordered multi-spin interactions previously studied as a model for sheared amorphous solids. The… 
The Irreversibility Transition in Amorphous Solids Under Periodic Shear
A fundamental problem in the physics of amorphous materials is understanding the transition from reversible to irreversible plastic behavior and its connection to the concept of yield. Currently,
Forced deterministic dynamics on a random energy landscape: Implications for the physics of amorphous solids.
This work shows that the phenomenology of amorphous plasticity can be described and explained using a simple model of forced dynamics on a multidimensional random energy landscape and the existence of limit cycles can be ascribed to confinement of the dynamics to a small part of the energy landscape.
Reversibility and criticality in amorphous solids
It is shown that at a critical strain amplitude the sizes of clusters of atoms undergoing cooperative rearrangements of displacements (avalanches) diverges, suggesting that, at least for highly jammed amorphous systems, the irreversibility transition may be a side effect of depinning that occurs in systems where the disorder is not quenched.
Memory formation in cyclically deformed amorphous solids and sphere assemblies
It is shown that single and multiple memories can be robustly retrieved through these different read protocols and measurements and that shear deformation by a larger amplitude always erases the stored memories.
Global memory from local hysteresis in an amorphous solid
A disordered material that cannot relax to equilibrium, such as an amorphous or glassy solid, responds to deformation in a way that depends on its past. In experiments we train a 2D athermal
Multiple memory formation in glassy landscapes
An interacting-rearrangement model for sheared solids shows multiple interaction-encoding memories and complex limit cycles, and shows that adding interactions between rearranging clusters overcomes deficiencies.
Cyclic annealing as an iterated random map.
Using numerical sampling, this work characterize the convergence properties of four types of random maps implementing successive physical restrictions and suggests further properties needed for a realistic mapping scheme.
Nanoscale origins of creep in calcium silicate hydrates
A three-staged incremental stress-marching technique is proposed to tie atomistic simulations and nanomechanical experimental measurements together and pave the way for the design of reduced aging construction materials and other disordered systems such as metallic and oxide glasses.
Embedding orthogonal memories in a colloidal gel through oscillatory shear.
Shear training memories in colloidal gels, which include an attractive interaction and network structure, are investigated, and it is discovered that such systems can support memories both along and orthogonal to the training flow direction.
Networks and Hierarchies: How Amorphous Materials Learn to Remember.
The slow and athermal deformations of amorphous solids are considered and how the ensuing sequence of discrete plastic rearrangements can be mapped onto a directed network is shown.


Oscillatory athermal quasistatic deformation of a model glass.
Computer simulations of oscillatory athermal quasistatic shear deformation of dense amorphous samples of a three-dimensional model glass former suggest that the same kind of transition found in driven colloidal systems is present in the case of amorphously solids.
Deformation and Failure of Amorphous, Solidlike Materials
Since the 1970s, theories of deformation and failure of amorphous, solidlike materials have started with models in which stress-driven, molecular rearrangements occur at localized flow defects via

The detailed analysis of particle hopping dynamics and the dynamic susceptibility indicates that mobile particles aggregate into clusters whose sizes increase at larger strain amplitudes, and the correlation between particle mobilities in consecutive time intervals demonstrates that dynamic facilitation becomes increasingly pronounced at larger strains.
Encoding of memory in sheared amorphous solids.
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, sharing the feature of
Onset of irreversibility and chaos in amorphous solids under periodic shear.
A fundamental problem in the physics of amorphous materials is understanding the transition from reversible to irreversible plastic behavior and its connection to yield. Currently, continuum material
Modeling the mechanics of amorphous solids at different length scale and time scale
We review the recent literature on the simulation of the structure and deformation of amorphous solids, including oxide and metallic glasses. We consider simulations at different length scale and
Signatures of distinct dynamical regimes in the energy landscape of a glass-forming liquid
Most materials attain a glassy state at low temperatures under suitable methods of preparation. This state exhibits the mechanical properties of a solid, but shows microscopic structural disorder,. A

Using continuum models, the interplay between applied strain and thermal fluctuations that governs the formation of thermally induced structural rearrangements in both colloidal and molecular glasses is elucidated.
