Scattering theory and its application to problems in modern atomic physics (1p)
Indhold This course will provide the necessary tools for a description and an understanding of a wide variety of dynamical processes involving electronic, atomic, and photonic collisions. First, the basic theory of non-relativistic scattering will be reviewed. Second, the formalism will be applied to illustrative examples developing the theory further. Specifically, the course will include:
- General scattering theory, including partial wave expansion, Green function method, Lippman-Schwinger equation, Born approximation, Coulomb potential, distorted wave theory, T- and S-matrix
- Density matrix formulation and coupled and uncoupled representations as illustrated by scattering by a spin-orbit potential
- Inelastic scattering, including excitation, ionization, the Bethe approximation, thresholds effects and exchange effects
- Cold collisions, including matter-antimatter collisions and ultra cold collisions in Bose condensates
- Scattering in strong laser fields, including laser-assisted electron-atom scattering, rescattering models of the plateau regions in high-harmonic generation and above-threshold-ionization
