Nonclassical heat flow in passive chiral solids is third rank, not odd (2412.08309v2)
Published 11 Dec 2024 in cond-mat.mtrl-sci and cond-mat.other
Abstract: Chiral, directionally isotropic gyroid lattices are observed to exhibit nonclassical thermal effects incompatible with an asymmetric ("odd") second rank conductivity tensor but consistent with a third rank tensor property that provides a curl term. The lattices are passive materials so no driving torques are needed to obtain transverse flow. A method for determination of the length scale associated with chirality is provided. The polymer gyroid lattice made by 3D printing is a metamaterial which allows chirality that is tunable by geometry.
