Impurity scattering in strongly correlated metals close to the Mott transition
Pascal Lederer, Marcelo J. Rozenberg
This work explores a simple approximation to describe isolated impurity scattering in a strongly correlated metal. The approximation combines conventional one electron scattering t…
Fractional excitations in the Luttinger liquid
K. -V. Pham, M. Gabay, P. Lederer
We reconsider the spectrum of the Luttinger liquid (LL) usually understood in terms of phonons (density fluctuations), and within the context of bosonization we give an alternative…
Wavefunctions for the Luttinger liquid
K. -V. Pham, M. Gabay, P. Lederer
Standard bosonization techniques lead to phonon-like excitations in a Luttinger liquid (LL), reflecting the absence of Landau quasiparticles in these systems. Yet in addition to th…
Jastrow-Luttinger Fractional Liquids
K. -V. Pham, M. Gabay, P. Lederer
In this paper, we present a description of Haldane's Luttinger liquid which parallels Laughlin's theory of the Fractional Quantum Hall (FQH) incompressible fluid, both exhibiting s…
Resistivity of Doped Two-Leg Spin Ladders
Gilson Carneiro, Pascal Lederer
In doped two-leg spin ladder systems, holes are expected to form charged bosonic pairs. We study charge transport in this system in the temperature range where the bosons can be de…
