Abstract

A new property of the charge collective mode in a 1D electron system is found. In the wave number region close to 2k_F (k_F 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.
