TIME AND LOCATION: Monday and Wednesday, 2:10-3:30 pm, Roessler 158.

We will spend the first five weeks of this course reviewing the fundamentals of superconductivity: Basic properties of a superconductor and how they contrast with a normal metal, London Theory, and BCS theory. In discussing the latter topic we will include a general introduction to second quantization and model Hamiltonians, and solve the BCS Hamiltonian both using the canonical transformation approach as well as the equation of motion method for the Green's function.

In the second five weeks we will go through different classes of superconductors, including the cuprates, heavy fermion systems, MgB2, and the iron-pnictides. The emphasis here will be on key experimental results and on simple theoretical pictures, eg the possibility that exchange of spin fluctuations replaces phonons as the "glue" in the cuprates.
