Clustering transitions in vibrofluidized magnetized granular materials
2003
Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics
We study the effects of long range interactions on the phases observed in cohesive granular materials. At high vibration amplitudes, a gas of magnetized particles is observed with velocity distributions similar to non-magnetized particles. Below a transition temperature compact clusters are observed to form and coexist with single particles. The cluster growth rate is consistent with a classical nucleation process. However, the temperature of the particles in the clusters is significantly lower
