Electronic excitations in three-dimensions are usually particle-like and well-described by the Landau Fermi liquid theory.  In 1D, however, strong correlations between electrons are enhanced, resulting in collective excitations that are sound-like waves of either density or spin.  These excitations may be understood by the Tomonaga-Luttinger liquid theory as bosonic density and spin waves arising from...
