Memory effects in schematic models of glasses subjected to oscillatory deformation

Giuseppe Foffi, Davide Fiocco

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 ...

Encoding of Memory in Sheared Amorphous Solids

Giuseppe Foffi, Davide Fiocco

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 a deformable energy landscape. When these systems are su ...

Aggregation dynamics, structure, and mechanical properties of bigels

Francesco Varrato, Giuseppe Foffi, Davide Fiocco

Recently we have introduced bigels, inter-penetrating gels made of two different colloidal species. Even if particles with simple short-range isotropic potential are employed, the selective interactions enable the tunability of the self-assembly, leading t ...

Oscillatory athermal quasistatic deformation of a model glass

Giuseppe Foffi, Davide Fiocco

We report computer simulations of oscillatory athermal quasistatic shear deformation of dense amorphous samples of a three-dimensional model glass former. A dynamical transition is observed as the amplitude of the deformation is varied: For large values of ...

Effective Forces in Square Well and Square Shoulder Fluids

Giuseppe Foffi, Davide Fiocco

We derive an analytical expression for the effective force between a pair of macrospheres immersed in a sea of microspheres, in the case where the interaction between the two unlike species is assumed to be a square well or a square shoulder of given range ...
