Untitled Document

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, freeelectron 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.



No. of Lectures
1 hr each

Symmetry and Physical Properties of Crystals Point groups, Bravais lattices, Space groups, Neumann’s Principle and tensor properties of crystalline solids, elements of group theory, diffraction of waves in periodic structures.
