Log-normal Superstatistics Reveals Statistical Resilience in the Panic Response of Confined Ants
A. Reyes, M. Curbelo, F. Tejera +4
We report the emergence of Log-normal Superstatistics in the collective motion of ants confined in a quasi-2D arena and exposed to a panic-inducing stimulus. A data-driven supersta…
Scale Invariant Avalanches: A Critical Confusion
Osvanny Ramos
The "Self-organized criticality" (SOC), introduced in 1987 by Bak, Tang and Wiesenfeld, was an attempt to explain the 1/f noise, but it rapidly evolved towards a more ambitious sco…
Avalanche prediction in Self-organized systems
O. Ramos, E. Altshuler, K. J. Maloy
It is a common belief that power-law distributed avalanches are inherently unpredictable. This idea affects phenomena as diverse as evolution, earthquakes, superconducting vortices…
Uphill solitary waves in granular flows
E. Martinez, C. Perez-Penichet, O. Sotolongo-Costa +4
We have experimentally observed a new phenomenon in the surface flow of a granular material. A heap is constructed by injecting sand between two vertical glass plates separated by…
Quasiperiodic events in an earthquake model
O. Ramos, E. Altshuler, K. J. Maloy
We introduce a modification of the OFC earthquake model [Phys. Rev. Lett. 68, 1244 (1992)] in order to improve resemblance with the Burridge and Knopoff mechanical model and with p…
On the interpretation of "off the edge" avalanches
O. Ramos, A. J. Batista-Leyva, E. Altshuler
We establish both experimentally and theoretically the relation between off the edge and internal avalanches in a sandpile model, a central issue in the interpretation of most expe…
