Long-time tails and cage effect in driven granular fluids
Andrea Fiege, Timo Aspelmeier, Annette Zippelius
We study the velocity autocorrelation function (VACF) of a driven granular fluid in the stationary state in 3 dimensions. As the critical volume fraction of the glass transition in…
Generalised Bose-Einstein phase transition in large- component spin glasses
T. Aspelmeier, M. A. Moore
It is proposed to understand finite dimensional spin glasses using a expansion, where is the number of spin components. It is shown that this approach predicts a replica…
Microscopic kinetics and time-dependent structure factors
T. Aspelmeier, B. Schmittmann, R. K. P. Zia
The time evolution of structure factors in the disordering process of an initially phase separated lattice depends crucially on the microscopic mechanism which drives the disorderi…
Free cooling of particles with rotational degrees of freedom
Timo Aspelmeier, Martin Huthmann, Annette Zippelius
Free cooling of granular materials is analyzed on the basis of a pseudo-Liouville operator. Exchange of translational and rotational energy requires surface roughness for spherical…
Universal aspects of vacancy-mediated disordering dynamics: the effect of external fields
Wannapong Triampo, Timo Aspelmeier, Beate Schmittmann
We investigate the disordering of an initially phase-segregated binary alloy, due to a highly mobile defect which couples to an electric or gravitational field. Using both mean-fie…
Cooling dynamics of a dilute gas of inelastic rods: a many particle simulation
Timo Aspelmeier, Götz Giese, Annette Zippelius
We present results of simulations for a dilute gas of inelastically colliding particles. Collisions are modelled as a stochastic process, which on average decreases the translation…
