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…
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…
