Abstract
In condensed matter physics there exists a great variety of electron
systems that can be considered as quasi-one-dimensional (Q1D), such as
conducting polymers, carbon nanotubes, and semiconductor heterostructures.
They combine the richness of observable physical properties with the possibility
of finding exact solutions to non-trivial interacting problems. The
very existence of such systems arises from confining electrical forces,
which prevent the lateral motion of electrons. These forces give
rise to a rather strong spin-orbit interaction which significantly changes
the properties of interacting Q1D systems, in particular breaks down the
traditional "Luttinger liquid" description and destroys the spin-charge
separation.
