Krapivsky, and Kirone Mallick Phys. Rev. E 107, 044129 (2023) – Published 27 April 2023 This article studies the dynamical properties of single-file Brownian particles interacting via a Riesz potential. The authors observe an anomalous scaling of the fluctuations of the current and the position of the particles with time when the interaction is long ranged, and a subdiffusive behavior for particles with short-range interactions that is reminiscent of fractional Brownian motion.     Editors' Suggestion Topological defect coarsening in quenched smectic- C films analyzed using artificial neural networks Ravin A. Chowdhury, Adam A. S. Green, Cheol S. Park, Joseph E. Maclennan, and Noel A. Clark Phys. Rev. E 107, 044701 (2023) – Published 3 April 2023 After quenching, a liquid crystal film might contain thousands of topological defects which annihilate during coarsening. The authors analyze high-speed video of the coarsening process using neural networks, and find agreement with theoretical predictions and simulations.     Editors' Suggestion Letter Effect of curvature on the diffusion of colloidal bananas Justin-Aurel Ulbrich, Carla Fernández-Rico, Brian Rost, Jacopo Vialetto, Lucio Isa, Jeffrey S. Urbach, and Roel P. A. Dullens Phys. Rev. E 107, L042602 (2023) – Published 21 April 2023 This letter describes an experimental study of diffusion of smoothly curved colloidal rods as a function of their opening angle. The authors measure translational and rotational diffusion of these colloidal bananas with opening angles ranging from 0o to nearly 360o. Their results demonstrate the impact of curvature on diffusive behavior of elongated colloidal particles.       American Physical Society: 1 Physics Ellipse, College Park, MD 20740 ©2023 American Physical Society | All rights reserved   You are receiving this email because you are subscribed to Table of Content alerts.
