Learning Outcomes

The student will learn the fundamentals of the highly nonlinear atomic and molecular response to intense light and the new physical processes that emerge, such as optical tunneling, high harmonic generation, highly efficient energy absorption by atoms and molecules, the application of strong laser fields to imaging molecular structures and dynamics. Through lectures, extensive hands-on exercises and projects the students will learn both the key physical concepts and theoretical tools including time-dependent quantum mechanics and wavepacket dynamics, Keldysh theory and strong-field S-matrix methods, time-dependent semiclassical methods and quantum trajectories, Kramers-Henneberger approach, methods for the numerical solution of the time-dependent Schroedinger equation in strong laser fields, and the applications of quantum chemistry methods to time-dependent molecular response including non-Hermitian quantum mechanics. At the end of the course, the students will be able to competently apply the above theoretical tools to analyse and design the experiments aimed at imaging electron dynamics in atoms and molecules.

Content

Nonlinear light-matter interaction: from one-photon to multi-photon processes. Electronic response to strong low-frequency fields: optical tunnelling and the Keldysh formalism. Above threshold ionization and related phenomena. Electron motion after strong-field ionization and its consequences: high harmonic generation, laser-induced electron diffraction and holography, correlated multi-electron processes. Ionization in circularly polarized fields and generation of attosecond spin-polarized electron beams. Attoclock and the tunnelling time problem. High harmonic spectroscopy in atoms and molecules: combining sub-angstrom spatial and sub-femtosecond temporal resolution. Generation and characterization of attosecond pulses and pulse trains. Time-resolved spectroscopy of electron dynamics using attosecond pulses. Ultrafast chirality: inducing and detecting electron currents in chiral molecules, extremely efficient chiral discrimination of molecules. Evolution of attosecond spectroscopy from atoms and molecules to solids: towards all-optical imaging of topological properties and phase transitions.
