一、課程說明(Course Description)
<br>The course provides an introduction to the quantum theory of many electron 
<br>systems, which can be metals or doped semiconductors. The students will learn 
<br>the standard perturbation theoretical technique, e.g., Feynman diagrammatic 
<br>method, for treating such systems.
<br>
<br>The students are required to have backgrounds in quantum mechanics at the 
<br>introductory level.
