  • Author(s): Cecilia Herrero and Ludovic Berthier We propose a computational strategy to quantify the temperature evolution of the timescales and length scales over which dynamic facilitation affects the relaxation dynamics of glass-forming liquids at low temperatures, which requires no assumption about the nature of the dynamics. In two glass mode… [Phys. Rev. Lett. 132, 258201] Published Fri Jun 21, 2024
  • Author(s): Pasquale Digregorio, Cecilia Rorai, Ignacio Pagonabarraga, and Federico Toschi We establish how active stress globally affects the morphology of disclination lines of a three-dimensional active nematic liquid crystal under chaotic flow. Thanks to a defect detection algorithm based on the local nematic orientation, we show that activity selects a crossover length scale in betwe… [Phys. Rev. Lett. 132, 258301] Published Tue Jun 18...
  • Author(s): Erik Thoms, Zijian Song, Kai Wang, and Simone Napolitano We determine the adsorption rate of polymer melts by means of measurements of molecular mobility. We show that the complex set of molecular rearrangements involved in the adsorption of polymers on flat surfaces can be modeled as an equilibration kinetics driven by the slow Arrhenius process (SAP), a… [Phys. Rev. Lett. 132, 248101] Published Fri Jun 14, 2024
  • Author(s): Bartosz Kaczmarski, Sophie Leanza, Renee Zhao, Ellen Kuhl, Derek E. Moulton, and Alain Goriely The extraordinary range of motions achieved by elephants’ trunks can be mimicked by a physical model that uses just three “muscles,” which could inspire robotic designs. [Phys. Rev. Lett. 132, 248402] Published Fri Jun 14, 2024
  • Author(s): Andrea Bonato, Michael Chiang, Dom Corbett, Sergey Kitaev, Davide Marenduzzo, Alexander Morozov, and Enzo Orlandini The 3D folding of a mammalian gene can be studied by a polymer model, where the chromatin fiber is represented by a semiflexible polymer which interacts with multivalent proteins, representing complexes of DNA-binding transcription factors and RNA polymerases. This physical model leads to the natura… [Phys. Rev. Lett...
  • Author(s): D. Riccobelli, P. Ciarletta, G. Vitale, C. Maurini, and L. Truskinovsky We argue that nucleation of brittle cracks in initially flawless soft elastic solids is preceded by a nonlinear elastic instability, which cannot be captured without accounting for geometrically precise description of finite elastic deformation. As a prototypical problem we consider a homogeneous el… [Phys. Rev. Lett. 132, 248202] Published Thu Jun 13, 2024
  • Author(s): Cristina Gavazzoni, Carolina Brito, and Matthieu Wyart We study the glass transition by exploring a broad class of kinetic rules that can significantly modify the normal dynamics of supercooled liquids while maintaining thermal equilibrium. Beyond the usual dynamics of liquids, this class includes dynamics in which a fraction $(1−{f}_{R})$ of the partic… [Phys. Rev. Lett. 132, 248201] Published Tue Jun 11, 2024
