Author(s): Hugues Chaté and Alexandre Solon We propose a hydrodynamic description of the homogeneous ordered phase of polar flocks. Starting from symmetry principles, we construct the appropriate equation for the dynamics of the Goldstone mode associated with the broken rotational symmetry. We then focus on the two-dimensional case considerin… [Phys. Rev. Lett. 132, 268302] Published Thu Jun 27, 2024

Author(s): Pablo Rojas, Oreste Piro, and Martin E. Garcia Common models of circadian rhythms are typically constructed as compartmental reactions of well-mixed biochemicals, incorporating a negative-feedback loop consisting of several intermediate reaction steps essentially required to produce oscillations. Spatial transport of each reactant is often repre… [Phys. Rev. Lett. 132, 268401] Published Thu Jun 27, 2024

Author(s): Tristan Jocteur, Shana Figueiredo, Kirsten Martens, Eric Bertin, and Romain Mari The yielding transition in athermal complex fluids can be interpreted as an absorbing phase transition between an elastic, absorbing state with high mesoscopic degeneracy and a flowing, active state. We characterize quantitatively this phase transition in an elastoplastic model under fixed applied s… [Phys. Rev. Lett. 132, 268203] Published Wed Jun 26...

Author(s): Shesha Gopal Marehalli Srinivas, Francesco Avanzini, and Massimiliano Esposito We identify the thermodynamic conditions necessary to observe indefinite growth in homogeneous open chemical reaction networks (CRNs) satisfying mass action kinetics. We also characterize the thermodynamic efficiency of growth by considering the fraction of the chemical work supplied from the surrou… [Phys. Rev. Lett. 132, 268001] Published Tue Jun 25...

Author(s): Takeshi Kawasaki and Kunimasa Miyazaki When slowly sheared, jammed packings respond elastically before yielding. This linear elastic regime becomes progressively narrower as the jamming transition point is approached, and rich nonlinear rheologies such as shear softening and hardening or melting emerge. However, the physical mechanism of… [Phys. Rev. Lett. 132, 268201] Published Tue Jun 25, 2024

Author(s): Rodrigo Saavedra, Gerhard Gompper, and Marisol Ripoll When their vision is not strictly aligned with their propulsion vector, active agents can spontaneously self-organize into large-scale swirling patterns. [Phys. Rev. Lett. 132, 268301] Published Tue Jun 25, 2024

Author(s): Cecilia Herrero and Ludovic Berthier We propose a computational strategy to quantify the temperature evolution of the timescales and length scales over which dynamic facilitation affects the relaxation dynamics of glass-forming liquids at low temperatures, which requires no assumption about the nature of the dynamics. In two glass mode… [Phys. Rev. Lett. 132, 258201] Published Fri Jun 21, 2024
