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 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 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 کاملOne-Dimensional Liquid ^{4}He: Dynamical Properties beyond Luttinger-Liquid Theory.
We compute the zero-temperature dynamical structure factor of one-dimensional liquid ^{4}He by means of state-of-the-art quantum Monte Carlo and analytic continuation techniques. By increasing the density, the dynamical structure factor reveals a transition from a highly compressible critical liquid to a quasisolid regime. In the low-energy limit, the dynamical structure factor can be described...
متن کاملLuminescence from highly excited nanorings: Luttinger liquid description
We study theoretically the luminescence from quantum dots of a ring geometry. For high excitation intensities, photoexcited electrons and holes form Fermi seas. Close to the emission threshold, the single-particle spectral lines aquire weak many-body satellites. However, away from the threshold, the discrete luminescence spectrum is completely dominated by many-body transitions. We employ the L...
