Objectives of course:
This course will deepen your understanding of the electronic
properties of solids already gained through Introduction to Condensed Matter,
and use this under- standing to elucidate the electrical, optical and magnetic
properties of crystalline solids. It will also give you an introduction to density
functional theory. The course will be complemented by the presentation of
examples of current solid-state research
