Since its discovery, the asymmetric Fano resonance has been a characteristic feature of
interacting quantum systems. The shape of this resonance is distinctively different from that …

Conventional optical components rely on gradual phase shifts accumulated during light
propagation to shape light beams. New degrees of freedom are attained by introducing …

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 …

Coinage metals, such as Au, Ag, and Cu, have been important materials throughout
history.(1) Although in ancient cultures they were admired primarily for their ability to reflect …

Matter structured on a length scale comparable to or smaller than the wavelength of light can
exhibit unusual optical properties. Particularly promising components for such materials are …

The field of chiral inorganic nanostructures is rapidly expanding. It started from the
observation of strong circular dichroism during the synthesis of individual nanoparticles …

When light interacts with a metal nanoparticle (NP), its conduction electrons can be driven
