OECS-10 is the tenth of a very successful series of conferences that started in 1987 in Rome, Italy, and is addressed to scientists who lead fundamental and applied research on the optical properties of excitons in novel condensed-matter nanostructures. The 2007 meeting will bring together a large representative of the world leading actors in this domain, with the aim of stimulating the exchange of ideas, promoting international collaborations, and coordinating research on the newest exciton-related issues such as quantum information science and exciton quantum-collective phenomena. In this edition we intend to focus on: - heterostructures of low dimensionality: quantum wells, quantum wires and quantum dots - polaritons - quantum optics with excitons and polaritons - many-body effects under coherent and incoherent excitation - coherent optical spectroscopy - quantum coherence and quantum-phase manipulation - Bose-Einstein condensation and other collective phenomena - excitons in novel materials
