Luttinger Liquid in a Solvable 2-dimensional Model. * Typeset Using Revt E X
We consider spinless electrons in two dimensions with the bare spectrum ǫ(p) = |px| + |py|. In momentum space, the interactions among electrons have a finite range q0, which is small compared to the Fermi momentum. A golden rule calculation of the electron lifetime indicates a breakdown of the Landau Fermi liquid in the model. At the one-loop level of perturbation theory, we show that the densi...
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...
متن کاملLuttinger-liquid instability in the one-dimensional t-J model.
We study the t-J model in one dimension by numerically projecting the true ground state from a Luttinger liquid trial wave function. We find the model exhibits Luttinger liquid behavior for most of the phase diagram in which interaction strength and density are varied. However at small densities and high interaction strengths a new phase with a gap to spin excitations and enhanced superconducti...
متن کاملLuttinger - liquid behavior of one - dimensional 3
The ground-state properties of one-dimensional 3He are studied using quantum Monte Carlo methods. The equation of state is calculated in a wide range of physically relevant densities and is well interpolated by a power-series fit. The Luttinger liquid theory is found to describe the long-range properties of the correlation functions. The density dependence of the Luttinger parameter is explicit...
متن کاملCrossover from Fermi Liquid to Non-Fermi Liquid Behavior in a Solvable One-Dimensional Model
We consider a quantum many-body problem in one-dimension described by a Jastrow type wavefunction, characterized by an exponent λ and a parameter γ. In the limit γ = 0 the model becomes identical to the well known 1/r2 pair-potential model; γ is shown to be related to the strength of a many body correction to the 1/r2 interaction. Exact results for the one-particle density matrix are obtained f...
