Description: In this course we will develop the method of diagrammatic perturbation theory for the many-body problem and cover some basic applications.  Following the main text (Negele and Orland), the functional integral approach will be used.

Prerequisites: Quantum Mechanics A&B, Statistical Mechanics.

Main Text: John W. Negele and Henri Orland, Quantum Many-Particle Systems (Addison-Wesley, 1988).  The course will cover Chapters 1,2,3 and 5 of this book.

ADA Statement: Students with disabilities needing academic accommodation should: (1) register with and provide documentation to the Student Disability Resource Center; (2) bring a letter to the instructor indicating the need for accommodation and what type. Please do this during the first week of class.

Honor Code: Students are expected to uphold the Academic Honor Code published in the Florida State University Bulletin and the Student Handbook. The Academic Honor Systems of Florida State University is based on the premise that each student has the responsibility to (1) uphold the highest standards of academic integrity in the student's own work, (2) refuse to tolerate violations of academic integrity in the university community, and (3) foster a high sense of integrity and social responsibility on the part of the university community.
