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…
Lifetime of the first and second collective excitations in metallic nanoparticles
Guillaume Weick, Rafael A. Molina, Dietmar Weinmann +1
We determine the lifetime of the surface plasmon in metallic nanoparticles under various conditions, concentrating on the Landau damping, which is the dominant mechanism for interm…
A Circuit Model for Domain Walls in Ferromagnetic Nanowires: Application to Conductance and Spin Transfer Torques
Peter E. Falloon, Rodolfo A. Jalabert, Dietmar Weinmann +1
We present a circuit model to describe the electron transport through a domain wall in a ferromagnetic nanowire. The domain wall is treated as a coherent 4-terminal device with inc…
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-…
Phase space signatures of the Anderson transition
Andre Wobst, Gert-Ludwig Ingold, Peter Hänggi +1
We use the inverse participation ratio based on the Husimi function to perform a phase space analysis of the Anderson model in one, two, and three dimensions. Important features of…
