Reply to Comment on "Quantum Force in a Superconductor"

A reply is made to Comment by D.P.Sheehan in which he takes notice that the quantum force introduced in my earlier paper A.V.Nikulov, Phys. Rev. B 64, 012505 (2001) challenges to the absolute status of the second law of thermodynamics. It is shown that the introduction of the quantum force explains only an experimental challenge to the second law. The observation of the persistent current at non-zero resistance R > 0 is experimental evidence of violation of the postulate saving the second law in the beginning of the 20 century. According to this postulate any Brownian motion is absolutely random whereas the persistent current at R > 0 is a regulated Brownian motion.
