Abstract
The statistics of the electric field in a one‐dimensional ``sheet'' plasma is studied. It is shown that the electric field as a function of the space coordinate is a Markov process, whose basic probabilities are related to the Fourier coefficients of certain functions that play an important role in the previously found development of the grand partition function. Some implications regarding the statistics of particle locations are explored. The one‐point probability distribution of the electric field is found to be asymptotically Gaussian in the plasma limit. It is pointed out that the one‐dimensional analog of the Holtsmark calculation leads to an incorrect conclusion because electrostatic shielding is not properly taken into account.
