Effective temperature in athermal systems sheared at fixed normal load.

We perform molecular dynamics simulations of repulsive athermal systems sheared at fixed normal load to study the effective temperature TL defined from time-dependent fluctuation-dissipation relations for density. We show that these systems possess two distinct regimes as a function of the ratio TS/V of the granular temperature to the potential energy per particle. At small TS/V, these systems ...

Athermal jamming versus thermalized glassiness in sheared frictionless particles.

Numerical simulations of soft-core frictionless disks in two dimensions are carried out to study the behavior of a simple liquid as a function of temperature T, packing fraction φ, and uniform applied shear strain rate γ[over ·]. Inferring the hard-core limit from our soft-core results, we find that it depends on the two parameters φ and T/γ[over ·]. Here T/γ[over ·]→0 defines the athermal limi...

Athermal Jamming vs Thermalized Glassiness in Sheared Frictionless Particles

Numerical simulations of soft-core frictionless disks in two dimensions are carried out to study behavior of a simple liquid as a function of thermal temperature T , packing fraction φ, and uniform applied shear strain rate γ̇. Inferring the hard-core limit from our soft-core results, we find that it depends on the two parameters φ and T/γ̇. T/γ̇ → 0 defines the athermal limit in which a shear dri...

Activated dynamics and effective temperature in a steady state sheared glass.

We conduct nonequilibrium molecular dynamics simulations to measure the shear stress sigma, the average inherent structure energy E{IS}, and the effective temperature T{eff} of a sheared model glass as a function of bath temperature T and shear strain rate gamma. For T above the glass transition temperature T0, the rheology approaches a Newtonian limit and T{eff}-->T as gamma-->0, while for T<T...

Effective temperature and jamming transition in dense, gently sheared granular assemblies.

We present extensive computational results for the effective temperature, defined by the fluctuation-dissipation relation between the mean square displacement and the average displacement of grains, under the action of a weak, external perturbation, of a sheared, bi-disperse granular packing of compressible spheres. We study the dependence of this parameter on the shear rate and volume fraction...
