SYTH 1: Terahertz Physics: Toward Probing and Controlling of Materials on the Nanoscale

Donnerstag, 15. März 2018, 09:30–12:15, H 0105

Electromagnetic radiation at terahertz (THz) frequencies is of central relevance for basic research and applications. Owing to its low photon energy (4.1 meV at 1 THz), ultrashort THz pulses are an excellent probe of the dynamics of many elementary excitations of solids, for instance phonons, conduction electrons, excitons and magnons. Highly intense THz pulses open up the fascinating possibility to not only probe solids but to even control these modes down to the nanoscale. The talks of this symposium will provide an overview over latest developments in the generation and detection of ultrashort THz pulses and their application in the probing and controlling of ultrafast motions of electrons, ions and spins in solids and at surfaces, with a spatial resolution down to the atomic scale.
