    • note
    • The core-filling material is removed slowly enough (100 ms) that the vortex core has time to shrink adiabatically to its final bare size, but rapidly enough that the initial location of the bare core is well correlated with the location of the original filled core.

    • note
    • We use phase-contrast imaging for both the in-trap and expansion images to simplify imaging procedures. When imaging the expanded atom cloud, we obtain good signal when the probe is detuned three linewidths from resonance.

    • note
    • Because of our low trapping frequencies (7.8 Hz), expansions are correspondingly slow. We get larger final spatial distributions by giving the atoms a 6 ms preliminary "squeeze"at high spring constant, followed by a 50 ms expansion period.
