OPTI 648

Advanced Optical Physics (3 units). Introduction to advanced theoretical techniques of modern optical physics and the application of these techniques to the discussion of selected problems of current interest. Prerequisite: OPTI 547.

Course Outline

A. Tools of Modern Optical Physics
  • Quantization of the electromagnetic field. QED in the Coulomb gauge.
  • Thermal fields, coherent states, squeezed and subpoissonian states.
  • Interaction between atoms and quantized fields: dressed states, Jaynes-Cummings model, spontaneous emission.
  • System-reservoir interactions: master equations, Fokker-Planck equations, quantum Langevin equations. Monte-Carlo wavefunction
    simulations.
  • Quasi-distribution functions: P- and Q-representations, Wigner distribution.
B. Selected Problems

  • Heisenberg-Langevin treatment of the damped harmonic oscillator.
  • Optical Bloch equations for a two-level atom, evolution of internal and external degrees of freedom, radiative forces, resonance fluorescence.
  • Dressed two-level atom, master equation, resonance fluorescence, dipole forces.
  • We may choose to work through one or more of the "exercises" in "Atoms and Photons" by Cohen-Tannoudji, Dupont Roc and Grynberg, or choose to study one or more current topics, such as
C. Quantum entanglement, EPR experiments and quantum computation
  • Bose-Einstein condensation and atom lasers
  • Optical lattices, quantum chaos and quantum transport
