  • Author(s): Hao Hu, Robert M. Ziff, and Youjin Deng We combine percolation theory and Monte Carlo simulation to study in two dimensions the connectivity of an equilibrium lattice model of interacting Janus disks which self-assemble into an orientationally ordered stripe phase at low temperature. As the patch size is increased or the temperature is lo… [Phys. Rev. Lett. 129, 278002] Published Thu Dec 29, 2022
  • Author(s): Qiwei Yu and Yuhai Tu We study the energy cost of flocking in the active Ising model (AIM) and show that, besides the energy cost for self-propelled motion, an additional energy dissipation is required to power the alignment of spins. We find that this additional alignment dissipation reaches its maximum at the flocking … [Phys. Rev. Lett. 129, 278001] Published Wed Dec 28, 2022
  • Author(s): Marc Besse, Hugues Chaté, and Alexandre Solon We study numerically the Toner-Tu field theory where the density field is maintained constant, a limit case of “Malthusian” flocks for which the asymptotic scaling of correlation functions in the ordered phase is known exactly. While we confirm these scaling laws, we also show that such constant-den… [Phys. Rev. Lett. 129, 268003] Published Fri Dec 23, 2022
  • Author(s): Billie Meadowcroft, Ivan Palaia, Anna-Katharina Pfitzner, Aurélien Roux, Buzz Baum, and Anđela Šarić The sequential exchange of filament composition to increase filament curvature was proposed as a mechanism for how some biological polymers deform and cut membranes. The relationship between the filament composition and its mechanical effect is lacking. We develop a kinetic model for the assembly of… [Phys. Rev. Lett. 129, 268101...
  • Author(s): Fernando Caballero and M. Cristina Marchetti We use a continuum model to examine the effect of activity on a phase-separating mixture of an extensile active nematic and a passive fluid. We highlight the distinct role of (i) previously considered interfacial active stresses and (ii) bulk active stresses that couple to liquid crystalline degrees… [Phys. Rev. Lett. 129, 268002] Published Thu Dec 22, 2022
  • Author(s): Bnaya Gross, Ivan Bonamassa, and Shlomo Havlin We study the critical features of the order parameter’s fluctuations near the threshold of mixed-order phase transitions in randomly interdependent spatial networks. Remarkably, we find that although the structure of the order parameter is not scale invariant, its fluctuations are fractal up to a we… [Phys. Rev. Lett. 129, 268301] Published Thu Dec 22, 2022
  • Author(s): François Boulogne, Frédéric Restagno, and Emmanuelle Rio The film surrounding a soap bubble can be up to 8 °C cooler than the environment, a finding that has implications for bubble stability. [Phys. Rev. Lett. 129, 268001] Published Mon Dec 19, 2022
