Tutorial topic: Theory of interacting electrons in electromagnetic fields
Lecture dates at ETH Zurich:
Tuesday, January 15, 09:15 - 12:00 and 13:15 - 14:00, 4 lectures
Wednesday, January 16, 09:15 - 12:00 and 13:15 - 15:00, 5 lectures
Abstract:
The theory of the interacting electron and electromagnetic fields will be developed within the Coulomb gauge. It will be shown that in the electric-dipole approximation, the minimal-coupling and multipolar formalisms lead, respectively, to the so-called velocity and length forms of the Hamiltonian. A focus of the course will be an introduction to electronic-structure theory based on the second quantization of the electron field. This includes a discussion of the concept of configuration interaction and of the Condon rules. The Hartree-Fock mean-field and its implications will be analyzed. A number of illustrative examples of electron correlation effects in photoabsorption will be presented.
The course will conclude with a discussion of atomic strong-field physics from first principles.
Paper handouts and a visitor certificate are available for registered people.
Additional handouts will be downloadable after the seminar.
