Comment on "Coherent Detection of Electron Dephasing'' [arXiv:0909.2197]
A.V. Nikulov
TL;DR
This paper critically examines a previous theoretical claim about electron reflection in Aharonov-Bohm rings, arguing it contradicts fundamental physics principles and challenging its validity.
Contribution
It provides a scientific critique showing the inconsistency of the earlier theoretical result with fundamental physical laws.
Findings
The previous theory contradicts momentum conservation.
The earlier result cannot conform with the Aharonov-Bohm effect.
The publication based on that theory is likely incorrect.
Abstract
It is shown that the theoretical result according to which electrons can be reflected because of magnetic flux in the Aharonov-Bohm ring contradicts to the fundamental law of momentum conservation and can not conform with the Aharonov-Bohm effect. Therefore a publication of Phys. Rev. Lett. [arXiv:0909.2197] based on this result can not be correct.
