Mean-field stationary state of a Bose gas at a Feshbach resonance
Andrew Carmichael, Juha Javanainen
We study the steady state of a zero-temperature Bose gas near a Feshbach or photoassociation resonance using a two-channel mean-field model that incorporates atomic and molecular c…
Simple Mean-Field Theory for a Zero-Temperature Fermi Gas at a Feshbach Resonance
Juha Javanainen, Marijan Kostrun, Matt Mackie +1
We present a simple two-channel mean field theory for a zero-temperature two-component Fermi gas in the neighborhood of a Feshbach resonance. Our results agree with recent experime…
Collective molecule formation in a degenerate Fermi gas via a Feshbach resonance
Juha Javanainen, Marijan Kostrun, Yi Zheng +6
We model collisionless collective conversion of a degenerate Fermi gas into bosonic molecules via a Feshbach resonance, treating the bosonic molecules as a classical field and seed…
Rapid Adiabatic Passage from an Atomic to a Molecular Condensate
Matt Mackie, Andrew Carmichael, Marijan Kostrun +5
We examine collective magnetoassociation of a Bose-Einstein condensate (BEC), focusing on rapid adiabatic passage from atoms to molecules induced by a sweep of the magnetic field a…
Landau-Zener Problem for Trilinear Hamiltonians
Artur Ishkhanyan, Matt Mackie, Andrew Carmichael +2
We consider a nonlinear version of the Landau-Zener problem, focusing on photoassociation of a Bose-Einstein condensate as a specific example. Contrary to the exponential rate depe…
