PHYS4141 Advanced Theoretical Physics (2012/13)
Quantum Theory in Condensed Matter
18 lectures in Michaelmas Term
Syllabus: Review of Bose-Einstein condensation in the ideal gas and in dilute atomic gases. Superfluidity, interactions, and excitations (phonons, rotons) in Helium II. Phenomenology of superconductivity. Ginzburg-Landau theory. Introduction to many-body quantum field theory in bosonic and fermionic systems. Phonons and Cooper pairs, BCS theory and quasiparticles. These will be developed in a rigerous and manthematical fashion.
