CoScaLi IV - Workshop on Collective Scattering of Light
May 9 - 12, 2016 | Ubatuba - SP Brazil
The role of coherences between atomic dipoles has gained an ever-increasing importance with the advent of ultracold atoms and large trapped ion systems. These allow to generate and manipulate correlations and entanglement between the particles, with many consequences for both applications (e.g., quantum information) and for the study of fundamental properties of matter. Light is the most important and versatile tool to manipulate matter in a controlled way, allowing today to address and manipulate single atoms and ions and their respective coherences.
This workshop addresses the properties of these many-body systems at the frontier between the microscopic and macroscopic realms. The coupling between light and an ensemble of classical or quantum scatterers, and the induced classical and quantum correlations, will be intensively discussed through lectures and informal discussions. Some of the main topics of interest are listed below:
Cooperative scattering
Anderson localization of light
Dicke super and subradiance
Mesoscopic physics with cold atoms
Multiple scattering of light
Ab initio models for light scattering
