Microscopic dynamics underlying the stress relaxation of arrested soft materials

J Song, Q Zhang, F de Quesada… - Proceedings of the …, 2022 - National Acad Sciences
Arrested soft materials such as gels and glasses exhibit a slow stress relaxation with a broad
distribution of relaxation times in response to linear mechanical perturbations. Although this …

Avalanches and non-Gaussian fluctuations of the global velocity of imbibition fronts

R Planet, S Santucci, J Ortín - Physical review letters, 2009 - APS
We present an experimental study of the global velocity V (t) of a viscous fluid interface
during forced-flow imbibition in a disordered medium. Our high resolution setup shows that …

Laser-induced heating for the experimental study of critical Casimir forces with optical trapping

IA Martinez, A Petrosyan, S Ciliberto - SciPost Physics, 2023 - scipost.org

Exceptionally Slow, Long-Range, and Non-Gaussian Critical Fluctuations Dominate the Charge Density Wave Transition

S Kalimuddin, S Chatterjee, A Bera, H Afzal, S Bera… - Physical Review Letters, 2024 - APS
(TaSe 4) 2 I is a well-studied quasi-one-dimensional compound long-known to have a
charge-density wave (CDW) transition around 263 K. We argue that the critical fluctuations …

Correlated Conductance Fluctuations Close to the Berezinskii-Kosterlitz-Thouless Transition<? format?> in Ultrathin NbN Films

The distribution of spatially averaged critical properties

ST Bramwell - Nature Physics, 2009 - nature.com
Critical properties throughout science are popularly associated with heavy-tailed
distributions, but experimental evidence indicates several alternative, and very different …

Critical slowing down of the charge carrier dynamics at the Mott metal-insulator transition

B Hartmann, D Zielke, J Polzin, T Sasaki, J Müller - Physical Review Letters, 2015 - APS
We report on the dramatic slowing down of the charge carrier dynamics in a quasi-two-
dimensional organic conductor, which can be reversibly tuned through the Mott metal …

Non-gaussian nature of fracture and the survival of fat-tail exponents

KT Tallakstad, R Toussaint, S Santucci, KJ Måløy - Physical review letters, 2013 - APS
We study the fluctuations of the global velocity V l (t), computed at various length scales l,
during the intermittent mode-I propagation of a crack front. The statistics converge to a non …
