Observartion of itinerant ferromagnetism in a strongly interacting Fermi gas of ultracold atoms

Ferromagnetism of delocalized (itinerant) fermions occurs due to repulsive interactions and the exchange energy which reduces the interaction energy for spin polarized domains due to the Pauli exclusion principle. At a critical interaction, given by the so-called Stoner criterion [1], they system spontaneously develops domains and becomes ferromagnetic. This, together with a suitable band structure...

Theoretical Studies of Collisional Processes in Cold and Ultracold Gases

Theoretical Studies of collisional processes and gases at ultracold and cold temperatures in research that is responsive to the experimental program. Scattering at low temperatures is sensitive to the interaction at large distances of the colliding species. We calculated the interactions at long-range of a pair of ytterbium atoms (P. Zhang and a. Dalgarno 2008)...
