An experimental <condensed matter physicist> who coauthored images of coherent <electron> flow from a <quantum point contact>. A charged scanning tip locally depleted a <two-dimensional electron gas> and backscattered carriers; recording the resulting <electrical conductance> change as the tip moved produced a spatial response map. The experiment revealed mode-dependent angular patterns and branching while probing <inelastic scattering>.<Imaging Coherent Electron Flow by B. J.
