E 107, 034137 (2023) – Published 27 March 2023  | Large deviation functions can be used to describe fluctuations in model nonequilibrium systems. The authors study the properties of a numerical method for estimating these functions, and test it by applying it to a random walk on a random graph. | | | | | | Featured in Physics Erwan Taillanter and Marc Barthelemy Phys. Rev. E 107, 034304 (2023) – Published 7 March 2023  | Researchers have identified the traffic thresholds at which cities build urban freeways and ring roads, which could help city administrators refine infrastructure plans. | | | | | | Editors' Suggestion Ruben W. Verweij, Julio Melio, Indrani Chakraborty, and Daniela J. Kraft Phys. Rev. E 107, 034602 (2023) – Published 6 March 2023  | Motivated by the topological constraints imposed on cyclic polymers, the authors studied experimentally and numerically a model system for ring polymers. Their model system was created from micron-sized silica particles surrounded by a lipid bilayer and flexibly linked through DNA strands inserted in the bilayer. They compared the conformation and diffusive behavior of rings of four to eight segments with the behavior of linear polymers. | | | | | | | |
