Theory of the splay nematic phase: Single versus double splay
Michely P. Rosseto and Jonathan V. Selinger
Phys. Rev. E 101, 052707 (2020)This paper uses numerical and analytical methods to examine the structure and stability of a recently discovered splay nematic phase of liquid crystals. Results show that a double-splay structure, which has a two-dimensional modulation of the director splay, generally has lower free energy than a single-splay structure which is modulated in one dimension. Previous experimental studies, however, found only the single-splay structure. Ways to reconcile the theoretical and experimental results are suggested.

Boids in a loop: Self-propelled particles within a flexible boundary
A. C. Quillen, J. P. Smucker, and A. Peshkov
Phys. Rev. E 101, 052618 (2020)Collective motion is a ubiquitous phenomenon in active physical systems, but it is still poorly understood. In this work, the authors investigate numerically the motion of self-propelled particles inside a flexible boundary, finding a rich variety of behaviors and several boundary shapes such as ovals and shapes with regular or irregular bulges.

Snapping of hinged arches under displacement control: Strength loss and nonreciprocity
Gabriele Librandi, Eleonora Tubaldi, and Katia Bertoldi
Phys. Rev. E 101, 053004 (2020)Arches have always been fascinating for their remarkable mechanical properties. The authors of this paper suggest that arches could even serve as the next generation of mechanical metamaterials by showing numerically and experimentally the rich dynamical behavior of hinged shallow arches, such as snapping between two configurations and suddenly losing strength.
EDITORS' SUGGESTION
Anisotropic odd viscosity via a time-modulated drive
Anton Souslov, Andrey Gromov, and Vincenzo Vitelli
Phys. Rev. E 101, 052606 (2020)An active fluid composed of spinning rods can be made to display nematic order by periodically varying the spinning rate. The authors study the mechanical properties of such an anisotropic driven fluid, and find anomalous behaviors that are not seen in equilibrium.
