• Author(s): D. Riccobelli, P. Ciarletta, G. Vitale, C. Maurini, and L. Truskinovsky We argue that nucleation of brittle cracks in initially flawless soft elastic solids is preceded by a nonlinear elastic instability, which cannot be captured without accounting for geometrically precise description of finite elastic deformation. As a prototypical problem we consider a homogeneous el… [Phys. Rev. Lett. 132, 248202] Published Thu Jun 13, 2024
  • Author(s): Cristina Gavazzoni, Carolina Brito, and Matthieu Wyart We study the glass transition by exploring a broad class of kinetic rules that can significantly modify the normal dynamics of supercooled liquids while maintaining thermal equilibrium. Beyond the usual dynamics of liquids, this class includes dynamics in which a fraction $(1−{f}_{R})$ of the partic… [Phys. Rev. Lett. 132, 248201] Published Tue Jun 11, 2024
  • Author(s): R. Belousov, S. Savino, P. Moghe, T. Hiiragi, L. Rondoni, and A. Erzberger Cellular Potts models are broadly applied across developmental biology and cancer research. We overcome limitations of the traditional approach, which reinterprets a modified Metropolis sampling as ad hoc dynamics, by introducing a physical timescale through Poissonian kinetics and by applying princ… [Phys.

  • Author(s): Matan Yah Ben Zion and Naomi Oppenheimer Short-range repulsion governs the dynamics of matter from atoms to animals. Using theory, simulations, and experiments, we find that an ensemble of repulsive particles spreads compactly with a sharp boundary, in contrast to the diffusive spreading of Brownian particles. Starting from the pair intera… [Phys. Rev. Lett. 132, 238201] Published Tue Jun 04, 2024
  • Author(s): R. Maire, A. Plati, M. Stockinger, E. Trizac, F. Smallenburg, and G. Foffi Absorbing phase transitions (APTs) are widespread in nonequilibrium systems, spanning condensed matter, epidemics, earthquakes, ecology, and chemical reactions. APTs feature an absorbing state in which the system becomes entrapped, along with a transition, either continuous or discontinuous, to an a… [Phys. Rev. Lett. 132, 238202] Published Tue Jun 04, 2024
  • Author(s): Bhavesh Gautam and Juho S. Lintuvuori The hydrodynamic stresses created by active particles can destabilize orientational order present in the system. This is manifested, for example, by the appearance of a bend instability in active nematics or in quasi-two-dimensional living liquid crystals consisting of swimming bacteria in thin nema… [Phys.
