The result of neglecting the ionization term in the fluid plasma-wall equations results in a criterion named for this man, which has been shown to forbid the existence of a patching point and which does not specify a sheath edge. That principle named for this man gives the minimum velocity for a particle entering the Debye sheath. He also gives his name to a phenomenon that scales with the reciprocal of the strength of the magnetic field, his namesake diffusion, and he lends his name to an effect wherein a magnetic vector potential affects a charged particle in the absence of a magnetic field

Aharonov. For 10 points, identify this American physicist who developed  a non-local hidden variables quantum mechanical interpretation wherein the wavefunction of an electron determines its motion by acting as a pilot wave.
