Natural flicker noise (“ {1}/{f}”) and superconductivity
Abstract
The connection between two, up till now, independent phenomena: natural flicker noise and superconductivity is considered. It is shown that the existence of natural flicker noise ensures the possibility of existence of superconductivity  the disappearance of electrical resistance and the screening of a magnetic field in the limit of zero frequency. The phase transition from the normal to the superconductive state is not discussed. Thus, we are assuming that, in particular by Cooper pair condensation, a macroscopic number of Bose charged particles exists. Only the states at temperatures much below the critical one are considered. The situation where the noise defines the possibility of the existence of a coherent state  the superconductivity state  is not paradoxical because the natural flicker noise is also a coherent state of the system.
