Query: Defect Saturation in a Rapidly Quenched Bose Gas   We investigate the saturation of defect density in an atomic Bose gas rapidly
cooled into a superfluid phase. The number of quantum vortices, which are
spontaneously created in the quenched gas, exhibits a Poissonian distribution
not only for a slow quench in the Kibble-Zurek (KZ) scaling regime but also for
a fast quench in which case the mean vortex number is saturated. This shows
that the saturation is not caused by destructive vortex collisions, but by the
early-time coarsening in an emerging condensate, which is further supported by
the observation that the condensate growth lags the quenching in the saturation
regime. Our results demonstrate that the defect saturation is an effect beyond
the KZ mechanism, opening a path for studying critical phase transition
dynamics using the defect number distribution.
