  • Finite-Disorder Critical Point in the Brittle-to-Ductile Transition of Amorphous Solids in the Presence of Particle Pinning

    Author(s): Anoop Mutneja, Bhanu Prasad Bhowmik, and Smarajit Karmakar Using particle based simulation of a model glass former, we demonstrate a transition from brittle yielding to ductile yielding in amorphous solids by introducing quenched disorder in the form of randomly pinned particles. The well-annealed samples, which exhibit brittle yielding, undergo a transitio… [Phys. Rev. Lett. 135, 198201] Published Thu Nov 06, 2025

  • Pure Hydrodynamic Instabilities in Active Jets of Puller Microalgae

    Author(s): Isabelle Eisenmann, Marco Vona, Nicolas Desprat, Takuji Ishikawa, Eric Lauga, and Raphaël Jeanneret Using phototaxis to control cell orientation, various instabilities can be induced in jets of motile microalgae. [Phys. Rev. Lett. 135, 198301] Published Thu Nov 06, 2025

  • Interdependent Scaling Exponents in the Human Brain

    Author(s): Daniel M. Castro, Ernesto P. Raposo, Mauro Copelli, and Fernando A. N. Santos We apply the phenomenological renormalization group to resting-state fMRI time series of brain activity in a large population. By recursively coarse graining the data, we compute scaling exponents for the series variance, log probability of silence, and largest covariance eigenvalue. The scaling exp… [Phys. Rev.

  • Non-Markovian Linear Vibrational Absorption Spectroscopy for Nonharmonic Bond Potentials: A Perturbative Approach

    Author(s): Hélène Colinet, Florian N. Brünig, and Roland R. Netz The dynamic coupling of a vibrating molecular bond to its responsive liquid environment can be described by non-Markovian friction in the framework of the generalized Langevin equation (GLE) and gives rise to line shifts as well as homogeneous and inhomogeneous spectral line broadening. By perturbat… [Phys. Rev. Lett. 135, 188002] Published Fri Oct 31, 2025

  • Toughness of Double Network Hydrogels: The Role of Reduced Stress Propagation

    Author(s): Samuel B. Walker and Suzanne M. Fielding Double network hydrogels show remarkable mechanical performance, combining high strength and fracture toughness with sufficient stiffness to bear load, despite containing only a low density of cross-linked polymer molecules in water. We introduce a simple mesoscale model of a double network material… [Phys. Rev. Lett. 135, 188201] Published Thu Oct 30, 2025

  • Rheologically Tuned Modes of Collective Transport in Active Viscoelastic Films

    Author(s): Henning Reinken and Andreas M. Menzel While many living biological media combine both viscous and elastic properties, most theoretical studies employ either purely fluid or solidlike descriptions. We here use a unified framework for active films on substrates capable of describing a range of viscoelastic behavior to explore the interpla… [Phys. Rev. Lett. 135, 188301] Published Wed Oct 29, 2025

  • Reentrant Transition to Collective Actuation in Active Solids with a Polarizing Field

    Author(s): Paul Baconnier, Mathéo Aksil, Vincent Démery, and Olivier Dauchot Collective actuation in active solids—the spontaneous coherent excitation of a few vibrational modes—emerges from feedback between structural deformations and the orientation of active forces. It is an excellent candidate as a basic mechanism for oscillatory dynamics and regulation in dense living s… [Phys. Rev. Lett. 135, 188302] Published Wed Oct 29, 2025
