Theoretical Program

We have extended our studies of collisional processes in gases at ultracold and cold temperatures in researches that are responsive to experiments. We have calculated the 2Sg+ and  2Su+ potential curves of the molecular ion Yb2+ and we have obtained the cross-sections for charge exchange of its several isotopes of Yb 2 + in the parent...

Co-trapping of Cold NH Molecules with N Atoms

A frontier in physics with cold polar molecules is the study of paths toward collisional cooling. Here we co-trap an very low polarizability atom along with a very “atom-like” polar molecule. Earlier work with He colliding with NH found that the inelastic processes were highly suppressed due to the small of the NH ground state...

Realization of a strongly interacting Bose-Fermi mixture from a two-component Fermi gas

Fermions are the fundamental building blocks of matter, whereas bosons emerge as composite particles. The simplest physical system to study the emergence of bosonic behavior is a two-component fermion mixture, where the composite boson is a dimer of the two different fermions.

Microfabricated Ion Trap Systems for Quantum Simulations

We have developed and tested a generation of ion traps, for the purpose of quantum information science and quantum simulations. These traps are based on semiconductor lithography, fabricated at MIT, and operated at liquid helium temperature. The traps enable systematic study of the behavior of the quantum state of trapped ions, near the surface of...
