• Author(s): Misaki Ozawa and Giulio Biroli We study the role of elasticity-induced facilitation on the dynamics of glass-forming liquids by a coarse-grained two-dimensional model in which local relaxation events, taking place by thermal activation, can trigger new relaxations by long-range elastically mediated interactions. By simulations an… [Phys. Rev. Lett. 130, 138201] Published Mon Mar 27, 2023
  • Author(s): Brato Chakrabarti, Michael J. Shelley, and Sebastian Fürthauer Many active particles, such as swimming micro-organisms or motor proteins, do work on their environment by going though a periodic sequence of shapes. Interactions between particles can lead to synchronization of their duty cycles. Here, we study the collective dynamics of a suspension of active par… [Phys. Rev.

  • Author(s): Yongick Cho and William M. Jacobs Unlike fluids at thermal equilibrium, biomolecular mixtures in living systems can sustain nonequilibrium steady states, in which active processes modify the conformational states of the constituent molecules. Despite qualitative similarities between liquid-liquid phase separation in these systems, t… [Phys. Rev. Lett. 130, 128203] Published Fri Mar 24, 2023
  • Author(s): Gess Kelly, Navid Bizmark, Bulbul Chakraborty, Sujit S. Datta, and Thomas G. Fai We use a theoretical model to explore how fluid dynamics, in particular, the pressure gradient and wall shear stress in a channel, affect the deposition of particles flowing in a microfluidic network. Experiments on transport of colloidal particles in pressure-driven systems of packed beads have sho… [Phys. Rev. Lett. 130, 128204] Published Fri Mar 24...
  • Author(s): Nika Kralj, Miha Ravnik, and Žiga Kos Active matter is naturally out of equilibrium which results in the emergence of diverse dynamic steady states, including the omnipresent chaotic state known as the active turbulence. However, much less is known how active systems dynamically depart out of these configurations, such as get excited or… [Phys. Rev. Lett. 130, 128101] Published Tue Mar 21, 2023
  • Author(s): Trevor J. Jones, Thomas Dupuis, Etienne Jambon-Puillet, Joel Marthelot, and P.-T. Brun Deployable structures capable of significant geometric reconfigurations are ubiquitous in nature. While engineering contraptions typically comprise articulated rigid elements, soft structures that experience material growth for deployment mostly remain the handiwork of biology, e.g., when winged ins… [Phys.
