Quantum Optics

Sep 1, 1996

I study the interaction of laser with matter, with a semi-classical description, namely laser is described by Maxwell equation and matter at quantum level via a density matrix formulation.

Part of my Habilitation thesis deals with the theme. I also wrote a master-level book on models in nonlinear and quantum optics, including numerical issues.

I also worked on models at meso-scopic scale.

  • Ferromagetics materials.
