Relative stability in nonuniform temperature
Abstract
Landauer has suggested that the relative stability of a particle diffusing in a bistable potential is affected by an intervening hot layer. We derive this effect both from thermodynamics and from the diffusion equation. For this purpose the proper form of the diffusion equation in a nonuniform medium is established for the case of a Brownian particle. If the diffusion takes place in a ring, the hot layer creates a steady current.

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.
