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…
1/f noise in experimental Sinai quantum billiards
E. Faleiro, U. Kuhl, R. A. Molina +3
It was recently conjectured that 1/f noise is a fundamental characteristic of spectral fluctuations in chaotic quantum systems. In this Letter we show that the level fluctuations o…
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-…
Oscillatory behavior and enhancement of the surface plasmon linewidth in embedded noble metal nanoparticles
Rafael A. Molina, Dietmar Weinmann, Rodolfo A. Jalabert
We study the Landau damping of the surface plasmon resonance of metallic nanoparticles embedded in different environments of experimental relevance. Important oscillations of the p…
