How fast is ultrafast spectroscopy?

The Heisenberg uncertainty principle prevents us from pinpointing an electron in real time with arbitrary accuracy. What this means is that if we were to shine light on an electron and excite it, we would not be able to follow its trajectory precisely. And yet, recent years have witnessed the development of so-called ultrafast spectroscopic techniques which allows us to indirectly reconstruct a movie of the elections evolution within a molecule. Peter Puschnig, Professor at University of Graz, Austria, will lead us through this fascinating world of ultrafast spectroscopy to hopefully answer fundamental (and cool) questions about electronic motions in real time.
