Les gaz de l’atmosphere

Manipulation des Interactions dans les Gaz Quantiques:

The interparticle interactions in ultracold atomic gases can be tuned using Fano–Feshbach scattering resonances, which occur in low–energy collisions between two atoms. These resonances are usually obtained using an external static magnetic field. They turn ultracold atomic gases into an experimental playground for the investigation of novel phases in which Quantum Physics plays a key role. The...

Simulation de la diffusion de la lumière et des gaz par techniques de Monte Carlo. (Simulation of light and gaz diffusion with Monte Carlo technics)

Realistic image synthesis requieres an accurate modelling of the interactions of light with matter (reflection, refraction, scattering) and of luminous energy exchanges between the objects of the scene. This modelling, very complex if no restrictive assumption is made, can be efficiently fulfilled with a Monte Carlo simulation. In the present work, we define first of all a complete scene illumi...
