  • Cooling in natural systems typically requires external contact with a cold reservoir, with the final temperature determined by the environment, as dictated by thermodynamics. The authors demonstrate a spontaneous, selfsustained frictional cooling effect driven by the interplay of activity, dry friction, and crowding.

  • Ultrafast spectroscopy enables characterization and control of non-equilibrium states. Here the authors introduce a stochastic thermodynamics approach to calculate entropy production in a material under ultrafast excitation, using ionic displacement data from time-resolved X-ray scattering experiments.

  • Active matter systems composed of self-propelled agents exhibit dynamical clustering. In this work, the authors demonstrate that inertia induces a solid-liquid transition within the cluster structure and suppresses wetting phenomena at the container boundary.

  • Einstein relations in non-equilibrium active matter systems break upon increase of fluctuations and changes in the system’s dissipative properties. By observing the tapping collisions of a tracer in a bath of vibrationally excited active granular particles, the authors propose a generalized active Einstein relation accounting for memory effects.

  • In many chiral particle systems, vortex patterns emerge in the velocity fields due to the alignment interactions, but these patterns are non-permanent and decohere quickly. The authors predict the spontaneous emergence of vortices with high dynamical coherence, and identify the transition between the regimes of constant and oscillating vorticity.
