Huse Phys. Rev. E 107, 024137 (2023) – Published 27 February 2023 In commonly used percolation models, bonds of a lattice are occupied randomly and one asks if a connected cluster is present. In this paper, the authors study models in which bonds are occupied according to a deterministic and quasiperiodic pattern rather than randomly, and they find critical behavior quite different from random percolation.     Editors' Suggestion Sampling rare event energy landscapes via birth-death augmented dynamics Benjamin Pampel, Simon Holbach, Lisa Hartung, and Omar Valsson Phys. Rev. E 107, 024141 (2023) – Published 28 February 2023 A common problem in simulations of complex systems is the separation of metastable states by high barriers that hinder transitions between the states. The authors address this by adapting a sampling algorithm that includes a birth-death process, and show that this scheme can efficiently sample energy landscapes with such barriers.     Editors' Suggestion Flow-network-controlled shape transformation of a thin membrane through differential fluid storage and surface expansion Yongtian Luo, Che-Ling Ho, Brent R. Helliker, and Eleni Katifori Phys. Rev. E 107, 024419 (2023) – Published 28 February 2023 Flows in a fluid network embedded in a thin material can change the shape of that material. Inspired by the unfolding of flower petals, the authors of this paper study this phenomenon using a simple model that couples hydraulic networks to deformation mechanics.     Editors' Suggestion Chemical Leslie effect in a chiral smectic-C★ film: Nonsingular target patterns Félix Bunel and Patrick Oswald Phys. Rev. E 107, 024703 (2023) – Published 22 February 2023 When particles are made to flow through a chiral liquid crystal phase, they can induce flows in the liquid crystal and as well as a rotation of the director. This paper describes experiments with a flux of ethanol through a chiral smectic-C* film, and gives an interpretation of the results in the context of the Leslie theory.     Editors' Suggestion Chemical Leslie effect in a chiral smectic-C* film: Singular target patterns Félix Bunel and Patrick Oswald Phys. Rev. E 107, 024704 (2023) – Published 22 February 2023 Ethanol flowing through a chiral smectic-C* film can produce roughly circular patterns, but under different conditions also spiral patterns. Further experiments show these patterns, and their theoretical explanation is confirmed.       American Physical Society: 1 Physics Ellipse, College Park, MD 20740 ©2023 American Physical Society | All rights reserved   You are receiving this email because you are subscribed to Table of Content alerts.
