*Título*: Long-range in light scattering by cold atoms

*Abstract*: The scattering  of light  by cold  atomic clouds, and many over
light scattering problems, is a long-range problem by nature. Indeed,
the light creates  an effective  interaction between  the particles,
which presents the slow decay of waves over large distances. This allows
to reach  a  strong  'long-range'  coupling  between  the  particles,
 a paradigmatic  example being  the mean-field  coupling of  atoms in
1D optical  cavities.  3D  systems  also  exhibit  strong
inter-particle coupling, with a 1/r decay over long distances. As a result
from this all-to-all strong coupling, a variety  of 'cooperative' effects
were observed in light scattering  by atomic  clouds, that  are the
signatures of  the presence of macroscopic modes.  In this presentation,
we  will discuss such  cooperative  phenomena  in large  atomic  clouds,
and the techniques and models to deal with them. These phenomena
include superradiance  and   subradiance, Mie scattering  and cooperative
radiation spectrum.

Estão todos convidados!
Abraço,

Sandro
