Equilibrium long-ranged charge correlations at the surface of a conductor coupled to electromagnetic radiation. II

Results of a previous paper with the same title are retrieved by a different method. A one-component plasma is bounded by a plane surface. The plasma is fully coupled to the electromagnetic field, therefore, the charge correlations are retarded. The quantum correlation function of the surface charge densities, at times different by t , at asymptotical large distances R, at inverse temperature beta , decays as -1(8pi{2}betaR{3}) , a surprisingly simple result: The decay is independent of Planck's constant variant Planck's over 2pi , the time difference t , and the velocity of light c. The present paper is based on the analysis of the collective vibration modes of the system.
