Disordered elastic systems and one-dimensional interfaces

E Agoritsas, V Lecomte, T Giamarchi - Physica B: Condensed Matter, 2012 - Elsevier
We briefly introduce the generic framework of disordered elastic systems (DES), giving a
short 'recipe'of a DES modeling and presenting the quantities of interest in order to probe the …

Interevent correlations from avalanches hiding below the detection threshold

S Janićević, L Laurson, KJ Måløy, S Santucci… - Physical review letters, 2016 - APS
Numerous systems ranging from deformation of materials to earthquakes exhibit bursty
dynamics, which consist of a sequence of events with a broad event size distribution. Very …

Experimental evidence for three universality classes for reaction fronts in disordered flows

S Atis, AK Dubey, D Salin, L Talon, P Le Doussal… - Physical review …, 2015 - APS
Self-sustained reaction fronts in a disordered medium subject to an external flow display self-
affine roughening, pinning, and depinning transitions. We measure spatial and temporal …

Connectivity enhancement due to film flow in porous media

M Moura, EG Flekkøy, KJ Måløy, G Schäfer… - Physical Review …, 2019 - APS
We study the effects of connectivity enhancement due to film flow phenomena on the
drainage of an artificial porous medium and the relative influence of gravity for such effects …

Straight versus spongy: Effect of tortuosity on polymer imbibition into nanoporous matrices assessed by segmentation-free analysis of 3D sample reconstructions

FV Luna, AK Maurya… - The journal of …, 2022 - ACS Publications
We comparatively analyzed imbibition of polystyrene (PS) into two complementary pore
models having pore diameters of∼ 380 nm and hydroxyl-terminated inorganic-oxidic pore …

Loss of memory of an elastic line on its way to limit cycles

E Agoritsas, J Barés - Physical Review E, 2024 - APS
Oscillatory-driven amorphous materials forget their initial configuration and converge to limit
cycles. Here we investigate this memory loss under a nonquasistatic drive in a minimal …

Capillary rise of yield-stress fluids

B Géraud, L Jørgensen, L Petit… - Europhysics …, 2014 - iopscience.iop.org
In this letter the capillary rise of yield-stress fluids is investigated experimentally. Contrary to
the case of simple fluids, the final height reached by yield-stress fluids weakly depends on …

Autocatalytic reaction fronts inside a porous medium of glass spheres

S Atis, S Saha, H Auradou, D Salin, L Talon - Physical review letters, 2013 - APS
We analyze experimentally chemical wave propagation in the disordered flow field of a
porous medium. The reaction fronts travel at a constant velocity that drastically depends on …

Seismiclike organization of avalanches in a driven long-range elastic string as a paradigm of brittle cracks

J Barés, D Bonamy, A Rosso - Physical Review E, 2019 - APS
Crack growth in heterogeneous materials sometimes exhibits crackling dynamics, made of
successive impulselike events with specific scale-invariant time and size organization …

Static fluctuations of a thick one-dimensional interface in the 1+ 1 directed polymer formulation

E Agoritsas, V Lecomte, T Giamarchi - … E—Statistical, Nonlinear, and Soft Matter …, 2013 - APS
Experimental realizations of a one-dimensional (1D) interface always exhibit a finite
microscopic width ξ> 0; its influence is erased by thermal fluctuations at sufficiently high …
