A complete understanding of the precipitous onset of slow dynamics in systems such as supercooled liquids requires making direct connections between dynamics and the underlying potential energy landscape. With the aid of a switch in ensembles, we show that it is possible to formulate a landscape-based mechanism for the onset of slow dynamics based on the rapid lengthening of the geodesic paths that traverse the landscape. We confirm the usefulness of this purely geometric analysis by showing that it successfully predicts the diffusion constants of a standard model supercooled liquid.
