So, they DO elaborate, but just a little. Nothing obviously about 'muh exceeding the critical field limit:

>A thin wire blocks the ‘‘coupling’’ beam from illumi-
nating the center of a magnetically trapped BEC
[Fig. 1(a)], to create a symmetric double light-roadblock.
We then inject two counterpropagating Gaussian-shaped
‘‘probe’’ pulses along the symmetry axis of the trap. The
pulses compress spatially by several orders of magnitude
via the slow-light technique [13] and ultimately fit entirely
inside the BEC.
