(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 &quot;imaging for electron vortices&quot; from…</p><p><a href="https://hackerpaper.kaipfister.de/p/2509.16321/">Paper and discussion history</a>.
