Condensed Matter Physics

Condensed Matter Physics. Instructor: Professor G. Rangarajan, Department of Physics, IIT Madras. This is an advanced course on condensed matter physics at postgraduate level and it is proposed to introduce students of physics to various fundamental concepts of condensed matter physics and materials science. Starting with an introduction to symmetry in crystals and phase transitions, the course will cover concepts of waves in periodic structures,vibrations of crystal lattices, free electron theory, band structure, optical, transport, dielectric and magnetic properties of metals, semiconductors, insulators and superconductors. Noncrystalline solids, defects in solids and quantum fluids will also be briefly discussed. (from nptel.ac.in)
