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...

Universal resource state for One-Way Quantum Computations

A fascinating model for quantum computing, other than the traditional quantum circuit model, is the “one-way” model that is based on simply doing single qubit measurements to a fixed, initial entangled quantum state of many qubits.  By feeding back measurement results to control the axis of subsequent measurements, any quantum circuit can be simulated and...
