  • Clogging transition of many particle systems flowing through bottlenecks 

    Zuriguel, Iker; Parisi, Daniel; Cruz Hidalgo, Raul; Lozano, Celia; Janda, Alvaro; Gago, Paula; Peralta, Juan; Ferrer, Luis; Pugnaloni, Luis; Clement, Eric; Maza, Diego; Pagonabarraga, Ignacio; Garcimartín, Angel (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, ...
  • Clogging transition of vibration driven vehicles passing through constrictions 

    Patterson, G.; Fierens, P.; Sangiuliano Jimka, F.; König, P.; Garcimartín, A.; Zuriguel, Iker; Pugnaloni, Luis; Parisi, D. (American Physical Society, 2017)
    We report experimental results on the competitive passage of elongated self-propelled vehicles rushing through a constriction. For the chosen experimental conditions, we observe the emergence of intermittencies similar to ...
  • Contact network topology in tapped granular media 

    Arévalo, Roberto; Pugnaloni, Luis; Zuriguel, Iker; Maza, Diego (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 

    Pastor, Jose; Garcimartín, Angel; Gago, Paula; Peralta, Juan; Martín Gomez, Cesar; Ferrer, Luis; Maza, Diego; Parisi, Daniel; Pugnaloni, Luis; Zuriguel, Iker (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 ...
  • Tapped granular packings described as complex networks 

    Arévalo, Roberto; Pugnaloni, Luis; Maza, Diego; Zuriguel, Iker (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 ...
