Abstract

We calculate the interliquid conductivity for Luttinger liquids, within the so-called “confinement” regime where interliquid hopping is completely incoherent. We argue that the interliquid conductivity behaves as σ⊥(ω)∼ω4α, where α is the Luttinger liquid exponent. We discuss the effect of finite temperature, which is found to introduce a coherent weight into the conductivity. These results are in good agreement with experimental measurements of the frequency dependent normal state c-axis conductivity in the high-temperature superconductors YBa2Cu3O 7−δ and La 2−xSr xCuO4.
