Abstract

The excess noise spectral density in a superconducting film above Tc with a current flow is calculated. This noise is caused by spontaneous generation and dissociation of fluctuational Cooper pairs. The fluctuations of the Cooper pair density lead to the fluctuations of their direct contribution to the current in the presence of an electric field (the regular Aslamazov-Larkin terms) and to fluctuations of normal electron conductivity (the anomalous Maki-Thompson terms). The anomalous contribution to the noise is inversely proportional to the pair-breaking energy. In the case of weak pair-breaking this contribution can be much larger than the equilibrium noise.
