J. Voit, CHARGE-SPIN SEPARATION AND NON-FERMI LIQUID PHYSICS IN THE NORMAL-STATE OF QUASI-1D CHARGE-DENSITY-WAVE SYSTEMS, Physica. C, Superconductivity, 282, 1997, pp. 1747-1748
Charge-spin separation shows up as a single singularity plus a finite
peak in the spectral function of Luttinger Liquids coupled to phonons,
consistent with experiments on K0.3MoO3. Though transport is insensit
ive to it, much can be learned from comparing T-dependences of charge
and spin conductivities.
