Internal Forces and the Magnetoconductivity of a Nondegenerate 2D Electron Fluid
The forces on individual electrons in an unscreened nondegenerate electron fluid, due to electron density fluctuations, have been calculated using Monte Carlo simulations and determined experimentally over a broad range of the plasma parameter Gamma. The experimental results are obtained from the magnetoconductivity sigma(B) measured for electrons on liquid helium below 1 K for B \leq 8 T. The magnitude and density dependence of sigma(B) are explained by the many-electron theory of magnetotransport. The internal electric fields found from the experiments are in excellent agreement with the simulations.
