Quantum Ratchets
Open accessAbstract
We investigate quantum Brownian motion in adiabatically rocked ratchet systems. Above a crossover temperature ${T}_{c}$ tunneling events are rare, yet they already substantially enhance the classical particle current. Below ${T}_{c}$, quantum tunneling prevails and the classical predictions grossly underestimate the transport. Upon approaching $T\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$ the quantum current exhibits a tunneling induced reversal, and tends to a finite limit.

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.
