Quantum Fluctuations in the Tunneling between Superconductors
Abstract
Quantum fluctuations in a microscopic model of a Josephson junction including dissipative effects, parametrized by $\ensuremath{\eta}=\frac{\ensuremath{\hbar}}{2\ensuremath{\pi}{e}^{2}R}$ with $R$ the resistance, are discussed. It is shown that the parameter space divides sharply into two regions: One in which scaling trajectories lead to a vanishing mean tunneling rate at $T=0$ and the other in which they do not.

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.
