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...

Spin Squeezing on an Atomic Clock Transition

Atomic clocks, the most accurate instruments ever developed, can now operate at the Standard Quantum Limit; their uncertainty dominated by the uncorrelated projection of individual atoms into eigenstates.  Using entanglement, quantum mechanics allows one to correlate the atoms so as to redistribute or squeeze such quantum noise, reducing the uncertainty in a variable of interest.

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.
