Luttinger 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 کاملSliding 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 کاملSpin resonance in a Luttinger liquid with spin-orbit interaction
Spin-orbit interaction in quantum wires leads to a spin resonance at low temperatures, even in the absence of an external dc magnetic field. We study the effect of electron-electron interaction on the resonance. This interaction is strong in quantum wires. We show that the electron-electron interaction changes the shape of the resonance curve and produces an additional cusp at the plasmon frequ...
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...
