 Optics of Conducting Polymers

The Nobel Prize in Chemistry was awarded in 2000 to Alan Heeger, Alan MacDiarmid, and Hideki Shirakawa for the discovery and development of conductive polymers.  This event brings attention to and gives an opportunity to review the two decades of intensive research in this field.  The talk will concentrate on two topics.  One is the optics of linear polymers, such as polyacethylene, the story of solitons, intragap states, and their experimental manifestations.  The second will be devoted to the modern stage of optical and electro-optical studies in conducting polymers.  The effects of long-range Coulomb interaction on the absorption by the bound and free electron-hole states and the recent experiments on phenyl-based polymers will be discussed.
