Author(s): Henry Alston, Raphaël Voituriez, and Thibault Bertrand Stochasticity is a defining feature of the pairwise forces governing interactions in biological systems—from molecular motors to cell-cell adhesion—yet its consequences on large-scale dynamics remain poorly understood. Here, we show that reciprocal but randomly fluctuating interactions between parti… [Phys. Rev. Lett. 136, 128303] Published Fri Mar 27, 2026

Author(s): Lucie Vovard, Alexis Viel, Estelle Bastien, Lou-Anne Goutier, Gaëtan Jardiné, Jérémie Margueritat, Sylvain Monnier, and Thomas Dehoux Probing forces, deformations, and mechanical properties of cells are the hallmark of mechanobiology. Many techniques have been developed to this end that are largely based on deforming the cells and measuring the reaction force. In cells, an alternative approach was implemented in the mid-2010s base…...

Author(s): Wenjie Wei, Shiyuan Hu, Wenlong Chen, Xiaobin Dai, Zheng Jiao, Fanlong Meng, and Li-Tang Yan Escape of many active systems over potential barriers is subject to hydrodynamic interactions, but little is known about the active hydrodynamics in such nonequilibrium escape processes. Here, we combine simulations and theoretical analysis to examine how the hydrodynamics impacts the physics contro… [Phys. Rev. Lett. 136, 128301] Published...

Author(s): Lokrshi Prawar Dadhichi, Suvendra K. Sahoo, K. Vijay Kumar, and Sriram Ramaswamy We show theoretically that an imposed uniaxial anisotropy leads to new universality classes for the dynamics of active particles suspended in a viscous fluid. In the homogeneous state, their concentration relaxes superdiffusively, stirred by the long-ranged flows generated by its own fluctuations, a… [Phys. Rev. Lett. 136, 128302] Published Tue Mar 24...

Author(s): Vasco C. Braz and N. A. M. Araújo The formation of sintering bridges in amorphous powders affects both flow behavior and perceived material quality. When sintering is driven by surface tension, bridges emerge sequentially, favoring contacts between smaller particles first. Predicting the connectivity percolation threshold is key to … [Phys. Rev.

Author(s): Wei Li, Zhibin Xu, Tim Still, Arjun G. Yodh, and Yilong Han Grain boundary (GB) premelting, the formation of liquid layers along GBs below the melting point, can significantly alter material properties. However, the phenomenon remains poorly understood due to observational challenges. We study GB premelting through both experiments using temperature-sensitiv… [Phys. Rev.

Author(s): Jing Yang, Bingxin Li, Samuel Mattoso, Ahmed Abdelkawy, Mira Todorova, and Jörg Neugebauer Large thermal fluctuations of the liquid phase obscure the weak macroscopic electric field that drives electrochemical reactions, rendering the extraction of reliable interfacial charge distributions from ab initio molecular dynamics extremely challenging. We introduce SMILE (Scalar Macro-dipole Int… [Phys. Rev. Lett. 136, 118001] Published...
