From reading the article, I think they mean “determined” in the sense of controlled. They changed the potential distribution in the electrodes, and the single-electron wavefunction changed in a controlled way. The “geometry” is presumably the spatial probability distribution, including the spin.
- HNLurker2 7y agoYes and more they know the precise geometry (position) less they know about momentum
- Koshkin 7y ago... except that in the given context 'geometry' does not mean position.
- ulises314 7y agoYes it does,from the abstract of the original article: "We show that in-plane magnetic-field-assisted spectroscopy allows extraction of the in-plane orientation and full 3D size parameters of the quantum mechanical orbitals of a single electron GaAs lateral quantum dot with subnanometer precision."
- Koshkin 7y agoThat can hardly be interpreted as talking about 'position.' Also, it helps to remember that 1 nanometer is about 10 atom sizes.
