  A contradiction of the Little-Parks experiment with the Ohm's law and other
fundamental laws is explained. This explanation shows that the Little-Parks
oscillations of the loop resistance are an experimental evidence of a direct
(non-chaotic) Brownian motion. The Langevin force is connected with a change of
the momentum circulation of superconducting pairs because of the quantization.
Its average value can be non-zero because of the quantization. The existence of
a direct Brownian motion contradicts to the principle on which the second law
of thermodynamic is based. Therefore the Little-Parks experiment is evidence of
a possibility of violation of the second law. In the last years other authors
have stated also violation of the second law in different quantum systems:
