• Author(s): David Head A family of marginally rigid (isostatic) spring networks with fractal structure up to a controllable length was devised, and the viscoelastic spectra ${G}^{*}(ω)$ calculated. Two nontrivial scaling regimes were observed, (i) ${G}^{′}≈{G}^{′′}∝{ω}^{\mathrm{Δ}}$ at low frequencies, consistent with $\m… [Phys. Rev. Lett. 129, 018001] Published Wed Jun 29, 2022
  • Author(s): Alexander Morozov When subjected to sufficiently strong velocity gradients, solutions of long, flexible polymers exhibit flow instabilities and chaotic motion, often referred to as elastic turbulence. Its mechanism differs from the familiar, inertia-driven turbulence in Newtonian fluids and is poorly understood. Here… [Phys. Rev. Lett. 129, 017801] Published Tue Jun 28, 2022
  • Author(s): Sachidananda Barik and Sayantan Majumdar Many dense particulate suspensions show a stress induced transformation from a liquidlike state to a solidlike shear jammed (SJ) state. However, the underlying particle-scale dynamics leading to such striking, reversible transition of the bulk remains unknown. Here, we study transient stress relaxat… [Phys. Rev.

  • Author(s): Yan-Wei Li, Yugui Yao, and Massimo Pica Ciamarra We demonstrate, via numerical simulations, that the relaxation dynamics of supercooled liquids correlates well with a plastic length scale measuring a particle’s response to impulsive localized perturbations and weakly to measures of local elasticity. We find that the particle averaged plastic lengt… [Phys. Rev. Lett. 128, 258001] Published Tue Jun 21, 2022
  • Author(s): Aina Ramamonjy, Julien Dervaux, and Philippe Brunet A population of photosynthetic algae has been shown to exhibit a highly nonlinear response to light, forming dynamic structures in light-intensity gradients. [Phys. Rev. Lett. 128, 258101] Published Tue Jun 21, 2022
  • Author(s): Yujie Jiang, Soichiro Makino, John R. Royer, and Wilson C. K. Poon Non-Brownian grains dispersed in a colloidal gel render the system rheologically bistable, switching between distinct solidlike and liquidlike states depending on shear rate. [Phys. Rev.

  • Author(s): Ikumi Kobayashi and Shin-ichi Sasa We present a simple model describing the assembly and disassembly of heteropolymers consisting of two types of monomers $A$ and $B$. We prove that no matter how we manipulate the concentrations of $A$ and $B$, it takes longer than the exponential function of $d$ to synthesize a fixed amount of the d… [Phys. Rev.
