The left diagram is included in the diffuson, whereas the right diagram is not.  The difference of inelastic rates between weak localization and conductance fluctuation is a consequence of the missing diagram.

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 2004

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 (7 problem sets over the semester.)  Instead of exams, there will be a project.  This will be chosen by the student in consultation with the instructor, and can be presented either as a lecture or as a paper.  The instructor will be happy to suggest and discuss topics for projects and to help students with the project work.

III. Grading: The grade will be based on homeworks (65%) and on the project (35%).

IV Required text: S. Doniach and E. H. Sondheimer, Green's Functions for Solid State Physicists, Imperial College Press, new edition, 1998 (paperback.)

V. 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.

VI.Americans with Disabilities Act: If you have a physical, psychological, medical or learning disability that may impact your course work, please contact Disability Support Services, ECC (Educational Communications Center) Building, room 128, (631) 632-6748.  They will determine with you what accommodations are necessary and appropriate.
