Anomalous transport in conical granular piles

Research output: Contribution to journalJournal articleResearchpeer-review


Experiments on 211-dimensional piles of elongated particles are performed. Comparison with previous experiments in 111 dimensions shows that the addition of one extra dimension to the dynamics changes completely the avalanche properties, with the appearance of a characteristic avalanche size. Nevertheless, the time which single grains need to cross the whole pile varies smoothly between several orders of magnitude, from a few seconds to more than 100 hours. This behavior is described by a power-law distribution, signaling the existence of scale invariance in the transport process.
