It is found that in the one dimensional excitation model deterministic quantum charge transport can take place due to the electrostatic field coupling of the interacting electron correlations with number density variations of the electron gas. A new expression for probability current is found to be valid for collective excitations in interacting electron gas. It is also revealed that the phase-space evolution of modified Wigner distribution function for linear quasiparticle excitations resembles that of the classical free particle. In other words, semiclassical linear evolution of collective excitations in interacting quantum electron gas is quite analogous to dynamics of classical system of particles in the absence of external forces, where the interparticle electrostatic forces play the analogous role of internal classical forces. It is shown that the electrostatic field of electrons when coupled to collective electron wavefunction can also lead to directly measurable macroscopic phenomena. It is remarked that the interacting system of electrons simultaneously exhibits microscopic and macroscopic effects that are linked through the dual lengthscale behavior of collective quantum electron excitations.
