Bulletin Description:  The course focuses on the many-particle aspects of solid state physics addressing classical topics such as superconductivity and the transport properties of disordered conductors, as well as more modern subjects including the fractional quantum Hall effect, dissipative quantum mechanics, and problems of mesoscopic physics. Both phenomenological and theoretical descriptions are discussed. Spring, 0-3 credits, ABCF grading

Prerequisite: Phy 555 or permission of instructor

Syllabus for Spring 2005

I. Aims of the course: The main topic is perturbation theory in many body systems.  The philosophy is to use the theory to describe real phenomena in solids, and to use simple model systems as guides to understanding real data.  The course will follow the text closely, including the topics of X-ray singularities, the Kondo problem, and superconductivity.

II. Procedures and Requirements: There will be homework problems assigned (6 problem sets over the semester.)

III. Grading: The grade will be based on homeworks.

IV. Required text: Quantum Theory of Many-Particle Systems by A. L. Fetter and J. D. Walecka, Dover, ISBN:  0486428273.

V. Supplemental texts: Methods of Quantum Field Theory in Statistical Physics, A.A. Abrikosov, L.P. Gorkov, I.E. Dzyaloshinski, Dover ISBN:  0486632288
                                        A Guide to Feynman Diagrams in the Many-Body Problem, Richard D. Mattuck, Dover, ISBN:  0486670473

VI. Academic Honesty:  Discussions with fellow students are strongly encouraged, but work which is submitted for grading must be in your own words.  You should review the definition of plagiarism.
