In this work [1], we describe and analyze theoretically the two techniques of spin-gradient thermometry and spin gradient demagnetization cooling developed earlier by our group [2, 3].

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)...
