Contact network topology in tapped granular media
(American Physical Society, 2013)
We analyze the contact network of simulated two-dimensional granular packings in different states of mechanical equilibrium obtained by tapping. We show that topological descriptors of the contact network allow one to ...
Experimental proof of faster is slower in systems of frictional particles flowing through constrictions
(American Physical Society, 2015)
The “faster-is-slower” (FIS) effect was first predicted by computer simulations of the egress of pedestrians through a narrow exit [D. Helbing, I. J. Farkas, and T. Vicsek, Nature (London) 407, 487 (2000)]. FIS refers to ...
Clogging transition of many particle systems flowing through bottlenecks
(Scientific Reports, 2014)
When a large set of discrete bodies passes through a bottleneck, the flow may become intermittent due to the development of clogs that obstruct the constriction. Clogging is observed, for instance, in colloidal suspensions, ...
Tapped granular packings described as complex networks
(Taylor and Francis, 2013)
We characterize the structure of simulated two-dimensional granular packings using con- cepts from complex networks theory. The packings are generated by a simulated tapping protocol, which allows us to obtain states in ...
