Theoretical Femtosecond Physics (Summer 2026)
Atoms and molecules in strong laser fields
Due to some "glitch" under selma, the lecture will start in the second week
of the lecture period, i.e., on the 21st of April
Lectures: Tuesday 9:20-10:50: BZW A120
Wednesday 9:20-10:50, every second week: SE2/103/U
Exercises: Wednesday 9:20-10:50, every second week: SE2/103/U
Vertiefungsvorlesung, 3 hours lecture and 1 hour exercise classes per week.
Laying the theoretical foundations for understanding modern laser-matter interaction phenomena in atomic and molecular systems.
Preliminary contents of the lecture: theory of ultrafast laser-matter interaction
- time-dependent Schrödinger equation, Dyson series, Magnus expansion, Floquet theory, split-operator method
- minimal coupling und two-level systems (TLS), rotating-wave approximation, pi-pulses, Landau-Zener transitions, counter-diabatic driving, Floquet energies of TLS
- atoms in ultrafast laser fields: generation of attosecond pulses, tunnel- and multiphoton-ionisation, strong-field approximation, simple-man model, half-cycle pulses
- molecules in ultrafast laser fields: Born-Oppenheimer approximation and potential energy surfaces, exact factorization, ionisation und dissociation of homonuclear molecules, two-dimensional spectroscopy, coherent control of molecular dynamics
This is also a general lecture for IMPRS-QDC: https://www.imprs-pks.mpg.de/events/lectures-1
