**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.

**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.
