Geometric control and memory in networks of bistable elements

Abstract

The sequential response of driven frustrated media encodes memory effects and hidden computational capabilities. While abstract hysteron models can capture these effects, they require phenomenologically introduced interactions, limiting their predictive power. Here we introduce networks of bistable elements - physical hysterons - whose interactions are controlled by the networks' geometry. These networks realize a wide range of previously unobserved exotic pathways, including those that surpass current hysteron models. Our work paves the way for advanced microscopic models of memory and the rational design of (meta)materials with targeted pathways and capabilities.
