Thermometry and Refrigeration in a Two-Component Mott Insulator of Ultracold Atoms

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 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)...

Spin gradient thermometry for ultracold atoms in optical lattices

A major goal of current research with ultracold atoms in optical lattices is the realization of magnetic ordering.  This requires temperatures on the order of the second order tunneling rate, J2/U where U is the interaction energy and J the tunneling amplitude.  Such temperatures are about ten times less than 1 nk, the lowest temperature...
