Schall Equilibrium gels provide physically attractive counterparts of nonequilibrium gels, allowing statistical understanding and design of the equilibrium gel structure. Here, we assemble two-dimensional equilibrium gels from limited-valency “patchy” colloidal particles and follow their evolution at the p… [Phys. Rev. Lett. 132, 078203...
  • Author(s): Yun Min Song, Sean Campbell, LieJune Shiau, Jae Kyoung Kim, and William Ott Genetic oscillations are generated by delayed transcriptional negative feedback loops, wherein repressor proteins inhibit their own synthesis after a temporal production delay. This delay is distributed because it arises from a sequence of noisy processes, including transcription, translocation, tra… [Phys. Rev. Lett. 132, 078402] Published Thu Feb 15, 2024
  • Author(s): Julio Melio, Silke E. Henkes, and Daniela J. Kraft Floppy microscale spring networks are widely studied in theory and simulations, but no well-controlled experimental system currently exists. Here, we show that square lattices consisting of colloid-supported lipid bilayers functionalized with DNA linkers act as microscale floppy spring networks. We … [Phys. Rev.

  • Author(s): Huijun Zhang, Qi Zhang, Feng Liu, and Yilong Han Characterizing the local structural evolution is an essential step in understanding the nature of glass transition. In this work, we probe the evolution of Voronoi cell geometry in simple glass models by simulations and colloid experiments, and find that the individual particle cages deform anisotro… [Phys. Rev. Lett. 132, 078201] Published Tue Feb 13, 2024
  • Author(s): Gianmarco Spera, Charlie Duclut, Marc Durand, and Julien Tailleur We study the impact of nematic alignment on scalar active matter in the disordered phase. We show that nematic torques control the emergent physics of particles interacting via pairwise forces and can either induce or prevent phase separation. The underlying mechanism is a fluctuation-induced renorm… [Phys. Rev. Lett. 132, 078301] Published Tue Feb 13, 2024
  • Author(s): L. Happel and A. Voigt Coordinated cellular movements are key processes in tissue morphogenesis. Using a cell-based modeling approach we study the dynamics of epithelial layers lining surfaces with constant and varying curvature. We demonstrate that extrinsic curvature effects can explain the alignment of cell elongation … [Phys. Rev. Lett. 132, 078401] Published Tue Feb 13, 2024
  • Author(s): Michael Czajkowski and D. Zeb Rocklin Mechanical metamaterials designed around a zero-energy pathway of deformation known as a mechanism, challenge the conventional picture of elasticity and generate complex spatial response that remains largely uncharted. Here, we present a unified theoretical framework to showing that the presence of … [Phys. Rev. Lett. 132, 068201] Published Thu Feb 08, 2024
