Glassiness, rigidity, and jamming of frictionless soft core disks.
The jamming of bidisperse soft core disks is considered, using a variety of different protocols to produce the jammed state. In agreement with other works, we find that cooling and compression can lead to a broad range of jamming packing fractions ϕ{J}, depending on cooling rate and initial configuration; the larger the degree of big particle clustering in the initial configuration, the larger ...
متن کاملDissipation and Rheology of Sheared Soft-Core Frictionless Disks Below Jamming
We use numerical simulations to investigate the effect that different models of energy dissipation have on the rheology of soft-core frictionless disks, below jamming in two dimensions. We find that it is not necessarily the mass of the particles that determines whether a system has Bagnoldian or Newtonian rheology, but rather the presence or absence of large connected clusters of particles. We...
متن کاملCritical scaling of shearing rheology at the jamming transition of soft-core frictionless disks.
We perform numerical simulations to determine the shear stress and pressure of steady-state shear flow in a soft-disk model in two dimensions at zero temperature in the vicinity of the jamming transition ϕ{J}. We use critical point scaling analyses to determine the critical behavior at jamming, and we find that it is crucial to include corrections to scaling for a reliable analysis. We find tha...
متن کاملAthermal 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...
متن کاملAthermal 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...
