Surface plasmon dynamics of simple metal clusters excited with femtosecond optical pulses.
We report a new mechanism on the dynamics of correlated electrons in simple metal clusters which manifests by a strong electron temperature dependence of the surface plasmon resonance spectral profile. This effect is revealed thanks to a theoretical approach based on the time-dependent local-density approximation at finite electronic temperature, and it should be experimentally observable using pump-probe femtosecond spectroscopy techniques.
