Spin-Orbit Effects in Atomic High-Harmonic Generation
Stefan Pabst, Robin Santra
Spin-orbit interactions lead to small energy gaps between the outer-most and shells of noble gas atoms. Strong-field pulses tunnel-ionize an electron out of eit…
Introducing many-body physics using atomic spectroscopy
Dietrich Krebs, Stefan Pabst, Robin Santra
Atoms constitute relatively simple many-body systems, making them suitable objects for developing an understanding of basic aspects of many-body physics. Photoabsorption spectrosco…
Strong-Field Many-Body Physics and the Giant Enhancement in the High-Harmonic Spectrum of Xenon
Stefan Pabst, Robin Santra
We resolve an open question about the origin of the giant enhancement in the high-harmonic generation (HHG) spectrum of atomic xenon around 100 eV. By solving the many-body time-de…
Atomic and molecular dynamics triggered by ultrashort light pulses on the atto- to picosecond time scale
Stefan Pabst
Time-resolved investigations of ultrafast electronic and molecular dynamics were not possible until recently. The typical time scale of these processes is in the picosecond to atto…
Adiabaticity and diabaticity in strong-field ionization
Antonia Karamatskou, Stefan Pabst, Robin Santra
If the photon energy is much less than the electron binding energy, ionization of an atom by a strong optical field is often described in terms of electron tunneling through the po…
