Course Objectives
This course introduces the theoretical framework for nonrelativistic many-particle systems, emphasizing both fermionic and bosonic cases. Students will develop a solid understanding of ground-state formalisms and Green’s function techniques as fundamental tools of many-body physics. The course further explores linear response theory and the emergence of collective modes, providing a unified description of how interacting particles give rise to macroscopic phenomena in condensed matter systems.
Course Content
Nonrelativistic many-particle systems, ground-state formalism, Green's function, Fermi systems, Bose systems, linear response and collective modes.
Course Learning Outcomes
By the end of this course, students will be able to:
- Describe the theoretical framework of nonrelativistic many-particle systems and distinguish between fermionic and bosonic cases.
 - Apply ground-state formalisms to analyze interacting quantum systems.
 - Use Green’s function methods to study single-particle and many-body properties.
 - Employ linear response theory to calculate susceptibilities and response functions.
 - Analyze the origin and behavior of collective modes in interacting Fermi and Bose systems.
