Spatio-temporal organization of correlated local activity within global avalanches in slowly driven interfaces Planet Latorre, Ramon López, Juan M. Santucci, Stéphane Ortín, Jordi, 1959- Física de partícules Experiments Particle physics Experiments We study the jerky response of slowly driven fronts in disordered media, just above the depinning transition. We focus on how spatially disconnected clusters of internally correlated activity lead to large-scale velocity fluctuations in the form of global avalanches, and identify three different ways in which local activity clusters may organize within a global avalanche, depending on distance to criticality. Our analysis provides new scaling relations between the power-law exponents of the statistical distributions of sizes and durations of local bursts and global avalanches. Fluid fronts of imbibition in heterogeneous media are taken as a case study to validate these scaling relations. 2019-05-03T10:10:10Z 2019-05-03T10:10:10Z 2018-07-18 2019-05-03T10:10:10Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0031-9007 https://hdl.handle.net/2445/132626 680785 eng Reproducció del document publicat a: https://doi.org/10.1103/PhysRevLett.121.034101 Physical Review Letters, 2018, vol. 121, num. 3, p. 034101 https://doi.org/10.1103/PhysRevLett.121.034101 (c) American Physical Society, 2018 info:eu-repo/semantics/openAccess 6 p. application/pdf application/pdf American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
