CATALOG DESCRIPTION: Basic optical spectroscopy; interband excitations and emissions; low dimensional systems; excitons; phonons; Boltzmann transport, phonon and defect scattering, quantum transport, transport in magnetic field, localization, Mott-insulator transition; photovoltaics.

PREPARATION: This course surveys modern (literature motivated) topics in optical & condensed phase physics; any motivated student interested in the the topics is likely to do well in this course. The majority of students tend to be upper-year graduate students from the physics department, but students from any department or level are welcome. To get the most out of the material, knowledge of electromagnetism and quantum mechanics is assumed. Students who have not taken these courses are advised to email the instructor before enrolling. Undergraduate-level introduction to solid satate physics 575(Solid State) is strongly recommended. As this course emphasizes literature appreciation rather than exam-style problem solving, excellent performance might be possible regardless of your background.

Recommended Textbooks: Optical Properties of Solids, Mark Fox, Oxford Press (2010).
Band Theory and Electronic Properties of Solids, John Singleton, Oxford Press (2010). [Ch 1, 6, 9]
Supporting text: Solid State Physics, Ashcroft and Mermin
