The electromagnetic radiation that reaches our eyes every moment rarely comes from its original source. Looking for a tree or the sky, we can see the sunlight scattered by a multitude of microscopic particles. Depending on the scatterers characteristics and their collective behavior, the properties of light transport can be drastically changed. This makes collective light scattering a problem of fundamental importance. On the other hand, clouds of cold atoms have proved to be versatile platforms that allow to simulate in the laboratory more complex systems, such as photonic crystals or astrophysical systems. Particularly interesting are the collective phenomena that arise in the presence of light, such as the emergence of light mediated forces, leading to what one can call "optical stress". This project aims at using cold atomic clouds to study the light transport properties in dense media, as well as understanding how the matter reorganization process alters this transport. First, we pretend to understand how the transport properties of light are affected by optical forces and how light influences the movement of atoms. Then, we seek to understand whether the reorganization in the presence of high densities of matter or photons can lead to some singular behaviors such as "photon bubbles". Finally, we aim to find regimes where processes of particles self-organization are triggered. (AU)
