  Spontaneous self-constraint in active nematic flows

  Active processes drive biological dynamics across various scales and include subcellular cytoskeletal remodelling, tissue development in embryogenesis and the population-level expansion of bacterial colonies. In each of these, biological (...)

  Static Bell test in pilot-wave hydrodynamics

  Since its discovery in 2005, the hydrodynamic pilot-wave system has provided a concrete macroscopic realization of wave-particle duality and concomitant classical analogs of a growing number of quantum effects. The question naturally arises as (...)

  Dynamical Facilitation Governs the Equilibration Dynamics of Glasses

  Convincing evidence of domain growth in the heating of ultrastable glasses suggests that the equilibration dynamics of supercooled liquids could be driven by a nucleation and growth mechanism. We investigate this possibility by simulating the (...)

  Soft jamming of viral particles in nanopores

  Viruses have remarkable physical properties and complex interactions with their environment. However, their aggregation in confined spaces remains unexplored, although this phenomenon is of paramount importance for understanding viral (...)

  Frugal random exploration strategy for shape recognition using statistical geometry

  Very distinct strategies can be deployed to recognize and characterize an unknown environment or a shape. A recent and promising approach, especially in robotics, is to reduce the complexity of the exploratory units to a minimum. Here, we show (...)

  Traveling fronts in vibrated polar disks: At the crossroad between polar ordering and jamming

  We investigate experimentally the collective motion of polar vibrated disks in an annular geometry, varying both the packing fraction and the amplitude of the angular noise. For low enough noise and large enough density, an overall collective (...)

  Model of Active Solids: Rigid Body Motion and Shape-Changing Mechanisms

  Active solids such as cell collectives, colloidal clusters, and active metamaterials exhibit diverse collective phenomena, ranging from rigid body motion to shape-changing mechanisms. The nonlinear dynamics of such active materials remains, (...)

  Time-encoded electrical detection of trace RNA biomarker by integrating programmable molecular amplifier on chip

  One of the serious challenges facing modern point-of-care (PoC) molecular diagnostic platforms relate to reliable detection of low concentration biomarkers such as nucleic acids or proteins in biological samples. Non-specific analyte-receptor (...)

  Pattern formation by turbulent cascades

  Fully developed turbulence is a universal and scale-invariant chaotic state characterized by an energy cascade from large to small scales at which the cascade is eventually arrested by dissipation1,2,3,4,5,6. Here we show how to harness these (...)

  Odd elasticity and topological waves in active surfaces

  Odd elasticity describes active elastic systems whose stress-strain relationship is not compatible with a potential energy. As the requirement of energy conservation is lifted from linear elasticity, new antisymmetric (odd) components appear in (...)
