We study the stress fluctuations in simulations of a two-dimensional amorphous solid under a cyclic drive. It is known that this system organizes into a reversible state for small driving amplitudes and remains in an irreversible state for high driving amplitudes, and that a critical driving amplitude separates the two regimes. Here we study the time series of the stress fluctuations below and above the reversible-irreversible transition. In the irreversible regime above the transition, the… Expand

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.

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. Expand

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 materialExpand
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.

Collective nonaffine displacements in amorphous materials during large-amplitude oscillatory shear.
It is found that the initial response to cyclic shear near the critical strain amplitude involves disconnected clusters of atoms with large nonaffine displacements, and the amplitude of shear stress oscillations decreases after a certain number of cycles, which is accompanied by the initiation and subsequent growth of a shear band.

Criticality and correlated dynamics at the irreversibility transition in periodically driven colloidal suspensions
One possible framework to interpret the irreversibility transition observed in periodically driven colloidal suspensions is that of a non-equilibrium phase transition towards an absorbing reversibleExpand
The yielding transition in amorphous solids under oscillatory shear deformation
Through extensive computer simulations for a wide range of system sizes, it is demonstrated that cyclically deformed model glasses exhibit a sharply defined yielding transition with characteristics that are independent of preparation history. Expand
Chaos and threshold for irreversibility in sheared suspensions
There is a concentration dependent threshold for the deformation or strain beyond which particles do not return to their starting configurations after one or more cycles, and the comparison with numerical simulations illuminates the connections between chaos, reversibility and predictability.

The onset of a typical plastic event is studied with precision, and it is shown that the mode of the system which is responsible for the loss of stability has structure in real space which is consistent with a quadrupolar source acting on an elastic matrix. Expand
Experimental realization of directed percolation criticality in turbulent liquid crystals.
Developing an experimental technique to create a seed of topological-defect turbulence by pulse laser, this report confirms in particular the rapidity symmetry, which is a basic but nontrivial consequence of the field-theoretic approach to DP. Expand
Reversible to irreversible flow transition in periodically driven vortices.
It is shown that periodically driven superconducting vortices in the presence of quenched disorder exhibit a transition from reversible to irreversible flow under increasing vortex density or cycle period, providing evidence that the onset of irreversible behavior is a dynamical phase transition.

Flux flow noise and dynamical transitions in a flux line lattice.
The results show a rapid decrease in the velocity correlation length, a measure of the spatial homogeneity of the moving flux line assembly, as the upper critical field is approached. Expand
