SI2610 Many Particle Physics
KTH Royal Institute of Technology
Recommended prerequisites: Good knowledge about all compulsory physics courses and statistical mechanics.
Second quantization, BCS theory and super conductivity, Greens functions and field theory, Feynman diagrams, Fermi systems, Linear response and collective modes, Bose systems and RKKY interaction.
The course gives the basis for modern condensed matter theory. Problems are studied that cannot be analyzed by starting from the properties of single atoms in a material, but from collective phenomena like superconductivity, which emerges when a large number of atoms are coupled together. In earlier courses in quantum mechanics, systems with a very small number of particles are treated. In statistical mechanics systems with many non-interacting bosons and fermions are studied. The aim in this course is to study a large number of interacting quantum mechanical particles. The goal is to give basic knowledge about a number of methods that have been developed to treat many particle systems. The most important applications are superconductivity and the electron gas.
