A theoretical framework called the chiral random walk bridges classical diffusion and quantum evolution to explain how robust edge currents emerge in dissipative chiral systems.

This research provides professionals in soft matter and microfluidics with a predictive toolkit to engineer transport pathways without external forces. By utilizing the 'bulk-boundary correspondence' from quantum mechanics, designers can create robust, one-way microscopic channels in bacterial or colloidal systems simply by patterning the local chirality. It offers a unifying mathematical language for disparate phenomena like odd viscosity in fluids and robust edge transport in topological materials.
