Phys. Rev. Lett. 98, 060406 (2007) [4 pages]Visualization of Vortex Bound States in Polarized Fermi Gases at UnitarityReceived 15 August 2006; published 8 February 2007 We theoretically analyze a single vortex in a spin polarized 3D trapped atomic Fermi gas near a broad Feshbach resonance. Above a critical polarization the Andreev-like bound states inside the core become occupied by the majority spin component. As a result, the local density difference at the core center suddenly rises at low temperatures. This provides a way to visualize the lowest bound state using phase-contrast imaging. As the polarization increases, the core expands gradually and the energy of the lowest bound state decreases. © 2007 The American Physical Society URL:
