Paper Abstract

A new property of the charge collective mode in a 1D electron system is found. In the wave number region close to 2kF (kF being the Fermi wave number) the mode frequency goes to zero, showing the soft mode behavior. In addition, the common 1D plasmon spectrum exists in the long-wave region. The soft mode is related to the short-range dynamic electron correlations in 1D and is absent in the systems of higher dimensionality. The dynamic correlations are described adequately in the frame of the Luttinger model.
