Dissipation and Rheology of Sheared Soft-Core Frictionless Disks
Daniel VÃ¥gberg, Peter Olsson, S. Teitel
We use numerical simulations to investigate the effect of different dissipative models on the shearing rheology of massive soft-core frictionless disks in two dimensions. We show t…
Correlation Lengths in the Vortex Line Liquid of a High Tc Superconductor
Peter Olsson, S. Teitel
We use the three dimensional uniformly frustrated XY model, as a model for a high temperature superconductor in an applied magnetic field, to explicitly measure the longitudinal co…
Kink-Antikink Unbinding Transition in the Two Dimensional Fully Frustrated XY Model
Peter Olsson, S. Teitel
We carry out the first numerical simulations to directly confirm the existence of a kink-antikink unbinding transition, T_w, along Ising-like domain walls in the two dimensional fu…
Diffusion and Velocity Auto-Correlation in Shearing Granular Media
Peter Olsson
We perform numerical simulations to examine particle diffusion at steady shear in a model granular material in two dimensions at the jamming density and zero temperature. We confir…
Asymmetric velocity correlations in shearing media
Peter Olsson
A model of soft frictionless disks in two dimensions at zero temperature is simulated with a shearing dynamics to study various kinds of asymmetries in sheared systems. We examine…
Vortex glass transitions in disordered three-dimensional XY models: Simulations for several different sets of parameters
Peter Olsson
The anisotropic frustrated 3D XY model with strong disorder in the coupling constants is studied as a model of a disordered superconductor in an applied magnetic field. Simulations…
