Optical properties of 2D systems with interacting electrons : proceedings of the NATO Advanced Research Workshop on Optical Properties of 2D Systems with Interacting Electrons, St. Petersburg, Russia, 13-16 June 2002

The book focuses on the following topics: Evolution of optical spectra from excitonic peaks to the Fermi-edge singularity; negatively and positively charged excitons; reconstructing one-particle and collective excitation spectra with increasing electron density; spatial inhomogeneity and carrier interaction in nanostructures; spin-sensitive interaction and spin-spin interaction in confined systems; many-particle effects in semimagnetic semiconductor heterostructures. Optical methods described include: photoluminescence spectroscopy; Raman spectroscopy; reflectivity; near-field spectroscopy; magneto-optics in magnetic fields up to 50 T; pico- and femtosecond time-resolved spectroscopy; polarized light spectroscopy; optically detected resonance spectroscopy under far-IR and microwave radiation.

More than 40 scientists from 14 countries participated and gave 24 lectures and 16 poster presentations. The main goal of theWorkshop was to bring togetherleading scientists working in the field of optical properties of correlated electron systems in semiconductor nanostructures and to organize a vital and informal discussions of newest results in the field. The location and the format of the Workshop provided an atmosphere of friendly and fruitful communications. It is important to note that the Workshop continued a series of meetings con­ cerning the same topic: Warsaw 1999, Wurzburg 2000 (NATO ARW), and Berlin 2001. The subject agenda of the ARW was focused on the following topics: Evolution of optical spectra from the excitonic peaks to the Fermi-edge singularity Negatively and positively charged excitons Reconstruction ofone-particle and collective excitation spectra with increase of the electron density (combined exciton-cyclotron resonance and shake-up processes) Effect of spatial inhomogeneity on the carrier interaction in nanostructures Spin-sensitive interaction and spin-spin interaction in confined systems Many-particle effects in semimagnetic semiconductor heterostructures Proceedings of the NATO Advanced Research Workshop, held in St. Petersburg, Russia, 13-16 June 2002
