The Harmony of Nature: The Secret of How Synchronized Frequencies Aid Digestion - Physics Unraveling the Mysteries of Digestion

A research team from UC San Diego has mathematically solved the phenomenon of intestinal peristalsis as "frequency synchronizing in a stepwise manner," explaining how food is transported and mixed in one direction. Using a Ginzburg–Landau model with a gradient applied to a non-uniform oscillator system, they identified the frequency "plateaus," the phase defects separating them, and the "renormalized negative diffusion" produced by nonlinear effects. The findings were published in Physical Review Letters on October 14, 2025. This research is expected to contribute to the understanding and diagnosis of gastrointestinal motility disorders and have implications for the analysis of synchronization in cerebral blood vessels.
