Feshbach Resonances and Medium Effects in ultracold atomic Gases
G. M. Bruun
We develop an effective low energy theory for multi-channel scattering of cold atomic alkali atoms with particular focus on Feshbach resonances. The scattering matrix is expressed…
Collective oscillations of a Fermi gas in the unitarity limit: Temperature effects and the role of pair correlations
S. Riedl, E. R. Sanchez Guajardo, C. Kohstall +6
We present detailed measurements of the frequency and damping of three different collective modes in an ultracold trapped Fermi gas of Li atoms with resonantly tuned interactio…
Quantum phases of a Two-Dimensional Dipolar Fermi Gas
G. M. Bruun, E. Taylor
We examine the superfluid and collapse instabilities of a quasi two-dimensional gas of dipolar fermions aligned by an orientable external field. It is shown that the interplay betw…
Probing spatial spin correlations of ultracold gases by quantum noise spectroscopy
G. M. Bruun, Brian M. Andersen, Eugene Demler +1
Spin noise spectroscopy with a single laser beam is demonstrated theoretically to provide a direct probe of the spatial correlations of cold fermionic gases. We show how the generi…
Multi-channel scattering and Feshbach resonances: Effective theory, phenomenology, and many-body effects
G. M. Bruun, A. D. Jackson, E. E. Kolomeitsev
A low energy effective theory based on a microscopic multi-channel description of the atom-atom interaction is derived for the scattering of alkali atoms in different hyperfine sta…
