Virtual electron diffusion during quantum tunneling of the electric charge
Abstract
We calculate the rate of the elastic macroscopic quantum tunneling of the electric charge (q-MQT) in a system of two small-area, normal, tunnel junctions in the Coulomb blockade regime. Despite the fact that the intermediate electron state on the central electrode of the system during the tunneling is virtual, the rate of the q-MQT depends crucially on the character of real electron motion through this electrode. Typically this motion is diffusive, so that the tunneling rate is determined by the process of ``virtual diffusion'' of electrons on the time scale of the inverse Coulomb energy of the system, \ensuremath{\Elzxh}/${\mathit{E}}_{\mathit{C}}$.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
