Interacting electron systems between Fermi leads: effective one-body transmissions and correlation clouds
Rafael A. Molina, Dietmar Weinmann, Jean-Louis Pichard
In order to extend the Landauer formulation of quantum transport to correlated fermions, we consider a spinless system in which charge carriers interact, connected to two reservoir…
Length-dependent oscillations of the conductance through atomic chains: The importance of electronic correlations
Rafael A. Molina, Dietmar Weinmann, Jean-Louis Pichard
We calculate the conductance of atomic chains as a function of their length. Using the Density Matrix Renormalization Group algorithm for a many-body model which takes into account…
Residual conductance of correlated one-dimensional nanosystems: A numerical approach
Rafael A. Molina, Peter Schmitteckert, Dietmar Weinmann +3
We study a method to determine the residual conductance of a correlated system by means of the ground-state properties of a large ring composed of the system itself and a long non-…
Effect of a lattice upon an interacting system of electrons: Breakdown of scaling and decay of persistent currents
Houman Falakshahi, Zoltan Adam Nemeth, Jean-Louis Pichard
For an interacting system of N electrons, we study the conditions under which a lattice model of size L with nearest neighbor hopping t and U/r Coulomb repulsion has the same groun…
Mesoscopic Wigner crystallization in two dimensional lattice models
Jean-Louis Pichard, Georgios Katomeris, Franck Selva
The quantum-classical crossover from the Fermi liquid towards the Wigner solid is numerically revisited, considering small square lattice models where electrons interact via a Coul…
Random Matrix Theory of Scattering in Chaotic and Disordered Media
Jean-Louis Pichard
We review the random matrix theory describing elastic scattering through zero-dimensional ballistic cavities (having chaotic classical dynamics) and quasi-one dimensional disordere…
