Cold material: dynamics, control and applications

Cold material: dynamics, control and applications

alt textWe have demonstrated over the last few years different ways to protect molecules from molecules against harmful collisions. These shielding means are now for the most part experimentally feasible. This opens the door to the quantum degeneracy regime, for the formation of Bose-Einstein condensates or degenerate Fermi gases. The macroscopic and collective aspects and collective aspects will become important and will guide the perspectives to be explored.

Controlled N-body physics: Building on our studies performed on 2 and 3 body systems of dipolar molecules, we will extend the formalism to many-body systems. Our approach will consist in adding the molecules one by one. Using the model we have studied, we will see if the protection of the molecules survives. We will explore the collective properties of of these gases and its control by making a link between our microscopic formalism in first quantization, and the macroscopic formalism in second quantization, generally used.

Controlled ultra-cold chemistry: In a similar way, we will start from our work done chemical reactions to explore the effect of the initial quantum preparation of the effect of electric and magnetic fields, confinements, on the final product distributions. of the products.

Molecular complexes: For non-reactant molecules in their ground state, the collisions are dominated by short-range complexes. These complexes are important for understanding the loss mechanism. For this purpose, we will explore the 4-body dynamics of such systems starting from the recently studied 3-body formalism.
