Author(s): S. N. Maharana, L. Negrojević, A. Comolli, and A. De Wit A chemical reaction involving a flowing fluid leads to a striking visual pattern—a result that could benefit research on other propagating fronts, such as flames. [Phys. Rev. Lett. 136, 068001] Published Fri Feb 13, 2026

Author(s): Tanmoy Sarkar and Matej Krajnc We find a reentrant columnar-to-squamous rigidity transition in three-dimensional (3D) epithelia, governed by volume and area elasticity. Our model maps to the classic 2D area- and perimeter-elasticity model but, unlike its 2D counterpart, shows compression-induced softening or stiffening, depending… [Phys. Rev.

Author(s): Linnea Heitmeier and Thomas Voigtmann We investigate the interface of a glass-forming fluid showing non-Newtonian rheology. By applying shear flow in the interface, we observe that the surface tension depends on the shear rate. Importantly, the standard way of determining surface tension from the pressure anisotropy caused by the interf… [Phys. Rev. Lett. 136, 068203] Published Wed Feb 11, 2026

Author(s): Ram Sudhir Sharma, Alexandre Leonelli, Kevin Zhao, Eckart Meiburg, and Alban Sauret The gravity-driven discharge of granular material through an aperture is a fundamental problem in granular physics and is classically described by empirical laws with different fitting parameters. In this Letter, we disentangle the mass flux into distinct velocity and packing contributions by combin… [Phys. Rev. Lett. 136, 068204] Published Wed Feb...

Author(s): Yuanfei Huang, Chengyu Liu, Bing Miao, and Xiang Zhou We present a general framework for deriving entropy production rates in active matter systems driven by non-Gaussian active fluctuations. Employing the probability-flow equivalence technique, we rigorously obtain an entropy production (EP) decomposition formula. We demonstrate that the EP, $\mathrm{… [Phys. Rev.

Author(s): Michio Tateno and Omar A. Saleh An experimental model system of DNA nanoparticles shows that the droplet size distribution can be controlled by the droplets’ phase separation ability. [Phys. Rev. Lett. 136, 068403] Published Wed Feb 11, 2026

Author(s): Jin-Bing Wu, Zhenghao Guo, Baoming Shi, Daoxing Luo, Lei Zhang, Yan-Qing Lu, and Wei Hu Topological multistability reflects the complexity of structure evolution inside ordered condensed matter. For a given thermodynamic system, the actual attained stable states decline sharply compared with the theoretical anticipation, which severely restricts the diversity of the material structure … [Phys.
