Solid State Physics

Solid State Physics. Instructor: Dr. Nirmal Ganguli, Department of Physics, IISER Bhopal. This course is designed to introduce the structure, electronic, and other fundamental properties of solids to the students. It is supposed to be the fundamental course on solid state physics, covering in detail the representation of crystal structure, symmetries in solid, x-ray diffraction, bonding, transport properties, electronic structure, vibration of the lattice, outline of magnetism, and superconductivity. We will carefully develop the concepts in logical steps and solve problems, resulting in a concrete understanding of the topics. While a course covering these topics is mandatory in almost every university around the world for the Physics students, Chemistry and Electrical Engineering students interested in research of condensed matter physics may benefit from the course.
