This workshop brings together world leaders and young researchers and students working in the multi-disciplinary field of terahertz (THz) dynamics in nanostructures. The 0.1 to 10 THz frequency range of the electromagnetic spectrum is where electrical transport and optical transitions merge, thus offering exciting opportunities to study a variety of novel physical phenomena. By combining THz technology and nanotechnology, we can advance our understanding of THz physics while improving and developing THz devices. In particular, recent advances in the study of THz dynamics in carbon nanomaterials -- carbon nanotubes and graphene -- have not only broadened our horizon of THz research but also generated new excitement regarding their exotic AC properties and potential towards novel applications. Topics to be covered at the meeting include:
