Adiabatic Phase Diagram of an Ultracold Atomic Fermi Gas with a Feshbach Resonance

S. Watabe, T. Nikuni, N. Nygaard +2

We determine the adiabatic phase diagram of a resonantly-coupled system of Fermi atoms and Bose molecules confined in the harmonic trap by using the local density approximation. Th…

Adiabatic Phase Diagram on Degenerate Fermi Gas with Feshbach-Resonance

S. Watabe, T. Nikuni, N. Nygaard +2

We determine the adiabatic phase diagrams for a resonantly-coupled system of Fermi atoms and Bose molecules confined in a harmonic trap by using the local density approximation. Th…

Theory of Feshbach molecule formation in a dilute gas during a magnetic field ramp

J. E. Williams, N. Nygaard, C. W. Clark

Starting with coupled atom-molecule Boltzmann equations, we develop a simplified model to understand molecule formation observed in recent experiments. Our theory predicts several…

Ultracold Fermion Cooling Cycle using Heteronuclear Feshbach Resonances

M. A. Morales, N. Nygaard, J. E. Williams +1

We consider an ideal gas of Bose and Fermi atoms in a harmonic trap, with a Feshbach resonance in the interspecies atomic scattering that can lead to formation of fermionic molecul…

Phase diagrams for an ideal gas mixture of fermionic atoms and bosonic molecules

J. E. Williams, N. Nygaard, C. W. Clark

We calculate the phase diagrams for a harmonically trapped ideal gas mixture of fermionic atoms and bosonic molecules in chemical and thermal equilibrium, where the internal energy…

Atom-molecule equilibration in a degenerate Fermi gas with resonant interactions

J. E. Williams, T. Nikuni, N. Nygaard +1

We present a nonequilibrium kinetic theory describing atom-molecule population dynamics in a two-component Fermi gas with a Feshbach resonance. Key collision integrals emerge that…
