PHY 403: Condensed Matter Physics (4)
Prerequisites: PHY 306: Statistical Mechanics
Learning Objectives:
The course objective is to introduce to the student the physical properties of solids including the electrical, magnetic, optical, thermal and mechanical properties. The structure, symmetry, and bonding in solids determine the properties of solids and the goal of this course is the development of student understanding of these impacts.
