25_18/2013Plasmonic Nanostructures: Chirality and Chiroptical Effects in Plasmonic Nanostructures: Fundamentals, Recent Progress, and Outlook (Adv. Mater. 18/2013)

Recent developments of bottom-up and topdown approaches for material design and fabrication at the nanoscale have resulted in a variety of chiral nanomaterials. Ventsislav K. Valev and co-workers highlight on page 2517 four different strategies used to achieve giant chiroptical effects in chiral nanostructures. Their nonlinear chiroptical behaviour arises from the nonlinear susceptibility tensor. For second harmonic generation, in the dipole approximation, this tensor has 3 by 3 by 3 elements and is represented in the cover image by the familiar Rubik's cube.
