Query: Self-consistent theory of current and voltage noise in multimode
  ballistic conductors   Electron transport in a self-consistent potential along a ballistic
two-terminal conductor has been investigated. We have derived general formulas
which describe the nonlinear current-voltage characteristics, differential
conductance, and low-frequency current and voltage noise assuming an arbitrary
distribution function and correlation properties of injected electrons. The
analytical results have been obtained for a wide range of biases: from
equilibrium to high values beyond the linear-response regime. The particular
case of a three-dimensional Fermi-Dirac injection has been analyzed. We show
that the Coulomb correlations are manifested in the negative excess voltage
noise, i.e., the voltage fluctuations under high-field transport conditions can
be less than in equilibrium.
