Electromagnetically induced transparency: from atoms to semiconductors

Description
Il seminario è un'iniziativa di Alumni SSC e del nodo di Catania di EPS Young Minds Abstract: Quantum coherence and interference can be used to control the light-matter interaction and the propagation of light in multilevel systems. A survey of one of the most attractive techniques, electromagnetically induced transparency (EIT), will be given from the discovery of coherent population trapping, through a few related milestones such as adiabatic transfer and amplification without inversion, up to the investigation of EIT proper. Our theoretical results on both cold atom systems and solid state systems, including new photonic crystal structures created via coherent optical nonlinearities, will be discussed.
