Among the topics are optical properties of nanostructured metamaterials, magnetic second-harmonic generation from interfaces and nanostructures, reflection anisotropy spectroscopy studies of thiolate/metal interfaces, the decisive role of interface phonons in polaron state formation in quantum nanostructures, and towards the ab initio calculation of the circular dichroism of peptides.
Other scientists have detected this difference, called "circular dichroism," in organic molecules' spectroscopic "fingerprints"-detailed maps of the wavelengths of light absorbed or reflected by the sample.
