ScholarlyArticle: "Supersonic flow and hydraulic jump in an electronic de Laval nozzle" (2025) https://arxiv.org/abs/2509.16321 https://arxiv.org/abs/2509.16321 : > The crossover from subsonic to supersonic flow coincides with a discontinuity in the local electrochemical potential, analogous to the hydraulic jump observed in supercritical classical fluids Gilmore et al. (1950). We identify the electronic shock through combined global transport and local Kelvin probe force microscopy (KPFM), confirming the presence of compressible electron flow Additional "imaging for electron vortices" from https://news.ycombinator.com/item?id=46919958 https://news.ycombinator.com/item?id=46919958 re: the kondo effect and hydrodynamics : > [ nanoscale scanning magnetometer, terahertz pump–probe spectroscopy ]
