  • Topologically Protected Transport of Cargo in a Chiral Active Fluid Aided by Odd-Viscosity-Enhanced Depletion Interactions

    Author(s): Qing Yang, Hongwei Zhu, Peng Liu, Rui Liu, Qingfan Shi, Ke Chen, Ning Zheng, Fangfu Ye, and Mingcheng Yang The discovery of topological edge states that unidirectionally propagate along the boundary of system without backscattering has enabled the development of new design principles for material or information transport. Here, we show that the topological edge flow supported by the chiral active fluid c... [Phys. Rev. Lett. 126...

  • Phase Diagram of Active Brownian Spheres: Crystallization and the Metastability of Motility-Induced Phase Separation

    Author(s): Ahmad K. Omar, Katherine Klymko, Trevor GrandPre, and Phillip L. Geissler Under the right conditions, self-propelled particles collectively transition from a state of liquid-gas coexistence to one where the particles can crystalize, according to simulations.

  • Topological Boundary Constraints in Artificial Colloidal Ice

    Author(s): Carolina Rodríguez-Gallo, Antonio Ortiz-Ambriz, and Pietro Tierno The effect of boundaries and how these can be used to influence the bulk behavior in geometrically frustrated systems are both long-standing puzzles, often relegated to a secondary role. Here, we use numerical simulations and “proof of concept” experiments to demonstrate that boundaries can be engin... [Phys. Rev. Lett. 126, 188001] Published Thu May 06, 2021

  • Cooperative Chain Dynamics of Tracer Chains in Highly Entangled Polyethylene Melts

    Author(s): M. Zamponi, M. Kruteva, M. Monkenbusch, L. Willner, A. Wischnewski, I. Hoffmann, and D. Richter According to the results of new neutron scattering experiments, polymer molecules in plastics move in ways that aren’t captured by commonly used models. [Phys. Rev. Lett. 126, 187801] Published Tue May 04, 2021

  • Breakdown of Ergodicity and Self-Averaging in Polar Flocks with Quenched Disorder

    Author(s): Yu Duan, Benoît Mahault, Yu-qiang Ma, Xia-qing Shi, and Hugues Chaté We show that spatial quenched disorder affects polar active matter in ways more complex and far reaching than heretofore believed. Using simulations of the 2D Vicsek model subjected to random couplings or a disordered scattering field, we find in particular that ergodicity is lost in the ordered pha... [Phys. Rev. Lett. 126, 178001] Published Wed Apr 28, 2021

  • Structural Landscapes in Geometrically Frustrated Smectics

    Author(s): Jingmin Xia, Scott MacLachlan, Timothy J. Atherton, and Patrick E. Farrell A free energy model of smectic liquid crystals successfully reproduces known structures and identifies new candidates in scenarios involving geometric frustration. [Phys. Rev. Lett. 126, 177801] Published Tue Apr 27, 2021

  • Collective Synchronous Spiking in a Brain Network of Coupled Nonlinear Oscillators

    Author(s): Vitaly L. Galinsky and Lawrence R. Frank A network of propagating nonlinear oscillatory modes (waves) in the human brain is shown to generate collectively synchronized spiking activity (hypersynchronous spiking) when both amplitude and phase coupling between modes are taken into account. The nonlinear behavior of the modes participating in... [Phys. Rev. Lett. 126, 158102] Published Fri Apr 16, 2021
