  The concept of quantum Fermi liquid for description of (quasi)-1D electronic
systems is recovered. The model of (quasi)-1D quantum Fermi liquid is developed
on the example of trans-polyacetylene and it is the generalization of
well-known model of organic (quasi)-1D conductors, elaborated by Su, Schrieffer
and Heeger (SSH-model). It is shown, that spin-charge separation effect can be
realized in (quasi)-1D quantum Fermi liquids. It has topological soliton origin
in distinction from spinon-holon spin-charge separation effect in
Tomonaga-Luttinger liquids and electronic systems like them. The model allows
to extend the limits of the applicability of SSH-model to the electron-electron
correlated (quasi)-1D-systems without restriction on electron-electron
interaction force. The (quasi)-1D- systems with strong electron-phonon
interaction and/or strong electron-photon interaction can be also described
within the framework of given 1D quantum Fermi liquid model. Practical
significance of the model proposed consists in the clarification of the nature
of charge and spin carriers and in the clarification of the origin of
mechanisms of quasiparticles' interaction in the (quasi)-1D-systems, which are
the objects of nanoelectronics, spintronics and the other modern nanotechnology
branches.
