• ### Low-Frequency Excess Vibrational Modes in Two-Dimensional Glasses

Author(s): Lijin Wang, Grzegorz Szamel, and Elijah Flenner The number of excess vibrational modes in glasses scales differently in two dimensions than it does in three. [Phys. Rev. Lett. 127, 248001] Published Tue Dec 07, 2021
• ### Wetting Transition of Active Brownian Particles on a Thin Membrane

Author(s): Francesco Turci and Nigel B. Wilding The conditions that make liquid stick to a permeable membrane could elucidate how bacteria form films, and help researchers design tiny swimming robots. [Phys. Rev. Lett. 127, 238002] Published Wed Dec 01, 2021
• ### Temperature Dependence of Polymer Network Diffusion

Author(s): Takeshi Fujiyabu, Takamasa Sakai, Ryota Kudo, Yuki Yoshikawa, Takuya Katashima, Ung-il Chung, and Naoyuki Sakumichi The swelling dynamics of polymer gels are characterized by the (collective) diffusion coefficient $D$ of the polymer network. Here, we measure the temperature dependence of $D$ of polymer gels with controlled homogeneous network structures using dynamic light scattering. An evaluation of the diffusi... [Phys. Rev. Lett...
• ### Susceptibility of Orientationally Ordered Active Matter to Chirality Disorder

Author(s): Bruno Ventejou, Hugues Chaté, Raul Montagne, and Xia-qing Shi We investigate the susceptibility of long-range ordered phases of two-dimensional dry aligning active matter to population disorder, taken in the form of a distribution of intrinsic individual chiralities. Using a combination of particle-level models and hydrodynamic theories derived from them, we s... [Phys. Rev. Lett. 127, 238001] Published Tue Nov 30, 2021
• ### Zwitterions Raise the Dielectric Constant of Soft Materials

Author(s): Wenwen Mei, August J. Rothenberger, Joshua E. Bostwick, Joshua M. Rinehart, Robert J. Hickey, and Ralph H. Colby The strong polar nature of bonded molecular pairs called zwitterions boosts the dielectric constants of polar fluids. [Phys. Rev. Lett. 127, 228001] Published Wed Nov 24, 2021
• ### Mutual Information Disentangles Interactions from Changing Environments

Author(s): Giorgio Nicoletti and Daniel Maria Busiello Mutual information provides a promising method for disentangling intrinsic from extrinsic sources of noise in biological systems. [Phys. Rev. Lett. 127, 228301] Published Mon Nov 22, 2021
• ### Microscopic Theory for the Rheology of Jammed Soft Suspensions

Author(s): Nicolas Cuny, Romain Mari, and Eric Bertin We develop a constitutive model allowing for the description of the rheology of two-dimensional soft dense suspensions above jamming. Starting from a statistical description of the particle dynamics, we derive, using a set of approximations, a nonlinear tensorial evolution equation linking the devia... [Phys. Rev. Lett. 127, 218003] Published Fri Nov 19, 2021
