Abstract
Based on the results of statistical quantum electrodynamics, it is shown that the Coulomb interaction potential has no Fourier component at a zero wave vector when considering the non-relativistic system of charged particles in a macroscopic volume. This result is of fundamental importance in the study of correlation functions of the Coulomb system, including that in the presence of a Bose–Einstein condensate.
