Author(s): Yuan Zhou, Lazaros Tsaloukidis, Jack Binysh, Yuchao Chen, Nikta Fakhri, Corentin Coulais, and Piotr Surówka Living materials such as membranes, cytoskeletal assemblies, cell collectives, and tissues can often be described as active solids—materials that are energized from within, with elastic response about a well-defined reference configuration. These materials often live in complex and curved manifolds,… [Phys. Rev. Lett. 137,...

Author(s): Jianhua Zhang, Jiaqi Si, Ning Xu, and Hua Tong While crystals are defined by periodic order, the nature of amorphous solids remains elusive due to their disordered, diverse, and nonequilibrium structures. Here, we focus on jammed elastic packings and systematically tune structure from crystalline to fully disordered to unveil the universal under… [Phys. Rev.

Author(s): Yuejun Shen, Zhiqiao Jiang, Yunfan Huang, Brittany M. Cleary, Yixing Jiang, Grant M. Rotskoff, and Aaron M. Lindenberg In a finite-time continuous phase transition, topological defects emerge as the system undergoes spontaneous symmetry breaking. The Kibble-Zurek mechanism predicts how the defect density scales with the quench rate. During such processes, dissipation also arises as the system fails to adiabatically … [Phys. Rev....

Author(s): Soumyadeep Mondal, Phanindra Dewan, Lakshman Santhosh Kumar, and Sumantra Sarkar We present a framework for mechanochemical self-organization in active solids where elasticity is reciprocally coupled to Hopf oscillators. Our model reveals a rich landscape of symmetry-protected phases identified through amplitude equations and group-theoretic analysis. We uncover a universal tran… [Phys. Rev.

Author(s): Florian Gomez and Ruedi Stoop For centuries, the human distinction between consonant and dissonant dyadic sounds (“c-d perception phenomenon”) has remained an unresolved puzzle, igniting novel directions in physics research. Here, we demonstrate that nonlinear sound processing by the network of activated cochlear amplifiers reve… [Phys. Rev. Lett. 137, 078402] Published Tue Aug 11, 2026

Author(s): Shoma Hara, Masazumi Okada, Keisuke Kittaka, Sho Tanami, Yuichi Iwasaki, Hiroaki Ishikawa, Kiwamu Yoshii, and Yutaka Sumino Nonreciprocal interactions have recently attracted growing interest in nonequilibrium physics. In particular, breaking action-reaction symmetry has been proposed as a mechanism for collective motion, yet controlled experimental realizations remain scarce. Here, we show that bidisperse colloidal susp… [Phys....

Author(s): Yusheng Shen, Yan Wen, Qirui Zhao, Pingbo Huang, Pik-Yin Lai, and Penger Tong Stretched exponential distributions of nonequilibrium steady-state fluctuations are ubiquitous in living and nonliving systems alike, yet their microscopic origins have remained elusive. In this Letter, we track the motion of three types of vesicles across different cell types and find that their tr… [Phys. Rev. Lett. 137, 068401] Published Tue Aug 04,...
