The vivid optical properties of noble metal nanoparticles have been an object of fascination
since ancient times. The ruby red of stained glass windows arises from gold nanoparticles …

Real-space grids are a powerful alternative for the simulation of electronic systems. One of
the main advantages of the approach is the flexibility and simplicity of working directly in real …

Using the TDLDA method, we investigate how the polarizability of the d electrons of the gold
atoms influences the electronic and optical properties of metallic nanoshells. It is shown that …

Clusters as mesoscopic particles represent an intermediate state of matter between single
atoms and solid material. The tendency to miniaturise technical objects requires knowledge …

We present recent theoretical investigations on the dynamics of metal clusters in contact with
an environment, deposited or embedded. This concerns soft deposition as well as irradiation …

Pseudopotential time-dependent density-functional theory (TDDFT) calculations are carried
out to investigate the optical absorption spectra of magic-number noble-metal nanoparticles …

Silver microclusters display giant dipole collective resonances with an unusual size
dependence of the resonance frequency. This behavior is due to the fact that the clusters …

Total-internal-reflection tip-enhanced Raman spectroscopy (TIR-TERS) imaging of amyloid-
β (Aβ1–42-L34T) fibrils is performed with nanoscale spatial resolution in water, using TERS …

The optical response of free and matrix-embedded gold metal clusters Au N is investigated
in the framework of the time-dependent local-density-approximation (TDLDA). The …

The absorption UV-visible spectra of noble metal clusters Cun, Agn, Aun, n= 2–9 and 20 are
investigated in the framework of the time-dependent density functional theory using the long …
