Time-Resolved Photoemission on the Attosecond Scale |
Speaker: | Renate Pazourek (Vienna University of Technology) |
Abstract: | One of the most fundamental processes in the interaction of light with matter is the photoelectric effect, i.e. the emission of an electron after the absorption of a photon. With the advent of ultrashort and well-controlled laser pulses photoemission can now be studied with unprecedented temporal resolution. The challenge lies in interpreting the timing information obtained by attosecond pump-probe experiments. One fundamental question is whether an electron is emitted instantaneously upon absorption of a photon or with a certain time shift. For an accurate theoretical description we numerically solve the time-dependent Schrödinger equation for one- and two-electron atoms and can show that, as long as all measurement-induced distortions can be quantified, the intrinsic (Eisenbud-Wigner-Smith) time delay of photoemission becomes accessible by attosecond pump-probe setups. |
