• Author(s): David Martin, Hugues Chaté, Cesare Nardini, Alexandre Solon, Julien Tailleur, and Frédéric Van Wijland We study the role of noise on the nature of the transition to collective motion in dry active matter. Starting from field theories that predict a continuous transition at the deterministic level, we show that fluctuations induce a density-dependent shift of the onset of order, which in turn changes ...

  • Author(s): Hyun Woo Cho, Guang Shi, T. R. Kirkpatrick, and D. Thirumalai The number of compact structures of a single condensed polymer (SCP), with similar free energies, grows exponentially with the degree of polymerization. In analogy with structural glasses (SGs), we expect that at low temperatures chain relaxation should occur by activated transitions between the com... [Phys. Rev.

The kinetic arrest...
  • Author(s): Chen Liu, Suman Dutta, Pinaki Chaudhuri, and Kirsten Martens We develop a framework to study the mechanical response of athermal amorphous solids via a coupling of mesoscale and microscopic models. Using measurements of coarse-grained quantities from simulations of dense disordered particulate systems, we present a coherent elastoplastic model approach for de... [Phys. Rev.

  • Author(s): Thomas Speck and Ashreya Jayaram When immersed into a fluid of active Brownian particles, passive bodies might start to undergo linear or angular directed motion depending on their shape. Here we exploit the divergence theorem to relate the forces responsible for this motion to the density and current induced by—but far away from—t... [Phys. Rev.
