Author(s): Benoît Mahault and Hugues Chaté Working in two space dimensions, we show that the orientational order emerging from self-propelled polar particles aligning nematically is quasi-long-ranged beyond ${ℓ}_{r}$, the scale associated to induced velocity reversals, which is typically extremely large and often cannot even be measured. Bel... [Phys. Rev. Lett. 127, 048003] Published Fri Jul 23, 2021

Author(s): Rahul N. Chacko, François P. Landes, Giulio Biroli, Olivier Dauchot, Andrea J. Liu, and David R. Reichman As a cooling liquid nears the glass transition temperature, the dynamic facilitation of heterogeneous rearrangements becomes increasingly long-ranged and elastically-mediated. [Phys. Rev.

Author(s): Tomer Markovich and Tom C. Lubensky In common fluids, viscosity is associated with dissipation. However, when time-reversal symmetry is broken a new type of nondissipative “viscosity” emerges. Recent theories and experiments on classical 2D systems with active spinning particles have heightened interest in “odd viscosity,” but a micro... [Phys. Rev.

Author(s): Ilya Svetlizky and Yael Roichman We examine the response of a quasi-two-dimensional colloidal suspension to a localized circular driving induced by optical tweezers. This approach allows us to resolve over 3 orders of magnitude in the Péclet number (Pe) and provide a direct observation of a sharp spatial crossover from far- to near... [Phys. Rev.

Author(s): Denis S. Goldobin, Matteo di Volo, and Alessandro Torcini Lorentzian distributions have been largely employed in statistical mechanics to obtain exact results for heterogeneous systems. Analytic continuation of these results is impossible even for slightly deformed Lorentzian distributions due to the divergence of all the moments (cumulants). We have solve... [Phys. Rev.

Author(s): Paolo Rissone, Eric I. Corwin, and Giorgio Parisi Correlation functions in static observables other than density support the hypothesis that randomly jammed packings are hyperuniform. [Phys. Rev. Lett. 127, 038001] Published Mon Jul 12, 2021
