Energy-Resolved Information Scrambling in Energy-Space Lattices
S. Pegahan, I. Arakelyan, J. E. Thomas
Weakly interacting Fermi gases simulate spin-lattices in energy-space, offering a rich platform for investigating information spreading and spin coherence in a large many-body quan…
Spin-Energy Correlation in Degenerate Weakly-Interacting Fermi Gases
S. Pegahan, J. Kangara, I. Arakelyan +1
Weakly interacting Fermi gases exhibit rich collective dynamics in spin-dependent potentials, arising from correlations between spin degrees of freedom and conserved single atom en…
Designer Spatial Control of Interactions in Ultracold Gases
N. Arunkumar, A. Jagannathan, J. E. Thomas
Designer optical control of interactions in ultracold atomic gases has wide application, from creating new quantum phases to modeling the physics of black holes. We demonstrate spa…
Fermi Gases in the Two-Dimensional to Quasi-Two-Dimensional Crossover
Chingyun Cheng, J. Kangara, I. Arakelyan +1
We tune the dimensionality of pancake-shaped strongly-interacting Li Fermi gas clouds from two-dimensional (2D) to quasi-2D, by controlling the ratio of the radial Fermi energy…
Two-field optical methods to control magnetic Feshbach resonances
A. Jagannathan, N. Arunkumar, J. A. Joseph +1
Using an optically-trapped mixture of the two lowest hyperfine states of a Li Fermi gas, we observe two-field optical tuning of the narrow Feshbach resonance by up to 3 G and a…
Optical Control of the Scattering Length and Effective Range for Magnetically Tunable Feshbach Resonances in Ultracold Gases
Haibin Wu, J. E. Thomas
We describe two-field optical techniques to control interactions in Feshbach resonances for two-body scattering in ultra-cold gases. These techniques create a molecular dark state…
Optical control of Feshbach resonances in Fermi gases using molecular dark states
Haibin Wu, J. E. Thomas
We propose a general method for optical control of magnetic Feshbach resonances in ultracold atomic gases with more than one molecular state in an energetically closed channel. Usi…
