Attosecond physics and the dream of an electron movie

by Prof. Eva Lindroth (Fysikum, Stockholm UNiversity)

Advances in laser technology have made it possible to produce light-pulses with a duration of only a few tens to a few hundreds of attoseconds. Since this is the time scale of electron dynamics it opens the exciting possibility to follow for example electron motion during a chemical reaction or the charge-migration that takes place before the nuclear motion in photo-induced processes. Exactly how this should be done is still the subject of intense research. In the talk I will discuss some of the methods that have been developed and how we can understand the time-domain measurement that has been performed for basic processes such as photoionization.
