Course description (課程目標)

凝態物理是一個範圍極廣並且與實驗關連性強的領域， 本課程為物理所的基礎課程，主要的目標是在使學生能 掌握凝體物理共通之基本原理，因而能進一步掌握與 了解凝體相關的實驗現象。
Condensed matter physics is a broad subject that is closely related to experiments. This course is an elmentary course particularly designed for physics graduates. Its purpose is to develop students' understanding of common principles involved in condensed matter so that students can further grasp and understand phenomena involved in condensed matter experiments.
