Sliding Luttinger liquid phases
We study systems of coupled spin-gapped and gapless Luttinger liquids. First, we establish the existence of a sliding Luttinger liquid phase for a system of weakly coupled parallel quantum wires, with and without disorder. It is shown that the coupling can stabilize a Luttinger liquid phase in the presence of disorder. We then extend our analysis to a system of crossed Luttinger liquids and est...
متن کاملCrossed sliding Luttinger liquid phase
We study a system of crossed spin-gapped and gapless Luttinger liquids. We establish the existence of a stable non-Fermi-liquid state with a finite-temperature, long-wavelength, isotropic electric conductivity that diverges as a power law in temperature T as T→0. This two-dimensional system has many properties characteristic of a true isotropic Luttinger liquid, though at zero temperature it be...
متن کاملLuttinger liquid with asymmetric dispersion
We present an extension of the Tomonaga-Luttinger model in which left and right-moving particles have different Fermi velocities. We compute the dispersion relations of collective modes, one-particle Green’s functions, momentumdistributions and conductivities. Studying these quantities as functions of both the velocities and the strength of the interaction we find a new region in the space of c...
متن کاملColloquium: The spin-incoherent Luttinger liquid
In contrast to the well-known Fermi-liquid theory of three dimensions, interacting one-dimensional and quasi-one-dimensional systems of fermions are described at low energy by an effective theory known as Luttinger liquid theory. This theory is expressed in terms of collective many-body excitations that show exotic behavior such as spin-charge separation. Luttinger liquid theory is commonly app...
متن کاملTransport in a one-dimensional Luttinger liquid
In this paper we review recent theoretical results for transport in a one-dimensional (1d) Luttinger liquid. For simplicity, we ignore electron spin, and focus exclusively on the case of a single-mode. Moreover, we consider only the effects of a single (or perhaps several) spatially localized impurities. Even with these restrictions, the predicted behavior is very rich, and strikingly different...
