    • Assuming an oscillating image charge of 0.1-1 electrons at 1 THz, we could expect an ac current on the order of 10-8 - 10-7 A per nanowire. In our case, the load of a typical microstrip line of 50Ω could still be considered as a short circuit with negligible feedback on the device.

    • In fact, even a single-Slater-determinant state might require a large CI expansion in an unsuitable single-particle basis. Here, the "single- particle entropy" - kB Tr (ρ ln ρ) could be used as a measure of true correlation within a given pure many-body state.
