Interchain conductivity of coupled Luttinger liquids and organic conductors
Abstract
We reconsider the theory of dc and ac interchain conductivity in quasi-one dimensional systems. Our results are in good agreement with the measured c-axis optical conductivity of (TMTSF)2ClO4 and suggest that the c-axis dc-conductivity of (TMTSF)2PF6 in the 150K < T < 300Kd$ range is dominated by precursor effects of Mott localization. The crossover from a Luttinger liquid at high energy to a Fermi liquid at low energy is also addressed, within a dynamical mean-field theory. Implications for the inter-chain resistivity and Drude weight in the Fermi liquid regime are discussed.
