Abstract
The quantum theory of noise developed in the preceding Letter is extended by showing that because of interaction with the electromagnetic field, an alternating current carried by a beam of electrons emerging from some scattering process will present phase fluctuations with a spectrum. These fluctuations are expected in any ac current. They have similar power spectra, also determined by infrared radiative corrections, to dc noise.
