    "abstract": "Fluctuations of the electromagnetic field produced by quantized matter in\nexternal electric field are investigated. A general expression for the power\nspectrum of fluctuations is derived within the long-range expansion. It is\nfound that in the whole measured frequency band, the power spectrum of\nfluctuations exhibits an inverse frequency dependence. A general argument is\ngiven showing that for all practically relevant values of the electric field,\nthe power spectrum of induced fluctuations is proportional to the field\nstrength squared. As an illustration, the power spectrum is calculated\nexplicitly using the kinetic model with the relaxation-type collision term.\nFinally, it is shown that the magnitude of fluctuations produced by a sample\ngenerally has a Gaussian distribution around its mean value, and its dependence\non the sample geometry is determined. In particular, it is demonstrated that\nfor geometrically similar samples, the power spectrum is inversely proportional\nto the sample volume. Application of the obtained results to the problem of\nflicker noise is discussed.",
