Phase diagram of a two-component Fermi gas with resonant interactions

The pairing of fermions is at the heart of superconductivity and superfluidity.  The stability of these pairs determines the robustness of the superfluid state, and the quest for superconductors with high critical temperature is a search for systems with strong pairing mechanisms. Ultracold atomic Fermi gases have emerged as a highly controllable model system for...

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...

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.

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...
