On random graphs and the statistical mechanics of granular matter
Johannes Berg, Anita Mehta
The dynamics of spins on a random graph with ferromagnetic three-spin interactions is used to model the compaction of granular matter under a series of taps. Taps are modelled as t…

Phase Transitions of Hard Disks in External Periodic Potentials: A Monte Carlo Study
W. Strepp, S. Sengupta, P. Nielaba
The nature of freezing and melting transitions for a system of hard disks in a spatially periodic external potential is studied using extensive Monte Carlo simulations. Detailed fi…

Anomalous aging phenomena caused by drift velocities
J. M. Luck, Anita Mehta
We demonstrate via several examples that a uniform drift velocity gives rise to anomalous aging, characterized by a specific form for the two-time correlation functions, in a varie…
