Conductivity between Luttinger liquids: coupled chains and bilayer graphene / V. Mastropietro. - In: PHYSICAL REVIEW. B, CONDENSED MATTER AND MATERIALS PHYSICS. - ISSN 1098-0121. - 84:3(2011 Jul), pp. 035109.1-035109.8.
Abstract:
The conductivity properties between Luttinger liquids are analyzed by exact renormalization-group methods. We prove that in a two chain system or in a model of bilayer graphene, described by two coupled Fermionic honeycomb lattices interacting with a gauge field, the transverse optical conductivity at finite temperature is anomalous and decreasing together with the frequency as a power law with a Luttinger liquid exponent.
