Generation of a neutral, high-density electron-positron plasma in the laboratory

Abstract

We report on the laser-driven generation of purely neutral, relativistic electron-positron pair plasmas. The overall charge neutrality, high average Lorentz factor (${\hat{I}}_{e/p}^3\approx 15$), small divergence ($\hat{I}{¸}_{e/p}\approx 10-20$ mrad), and high density ($n_{e/p}\simeq 10^{15}$cm${}^{-3}$) of these plasmas open the pathway for the experimental study of the dynamics of this exotic state of matter, in regimes that are of relevance to electron-positron astrophysical plasmas.
