  These are extended lecture notes of the quantum mechanics course which I am
teaching in the Weizmann Institute of Science graduate physics program. They
cover the topics listed below. The first four chapter are posted here. Their
content is detailed on the next page. The other chapters are planned to be
added in the coming months.
  1. Motion in External Electromagnetic Field. Gauge Fields in Quantum
Mechanics.
  2. Quantum Mechanics of Electromagnetic Field
  3. Photon-Matter Interactions
  4. Quantization of the Schr\"odinger Field (The Second Quantization)
  5. Open Systems. Density Matrix
  6. Adiabatic Theory. The Berry Phase. The Born-Oppenheimer Approximation
  7. Mean Field Approaches for Many Body Systems -- Fermions and Bosons
