摘要: We describe the creation of localized density perturbations, or ion holes, in an ultracold neutral plasma hydrodynamic regime, and show that holes propagate at local acoustic wave speed. also observe process hole splitting, which results from formation a depletion initially rest plasma. One-dimensional, two-fluid simulations well. Measurements velocity distribution effects confirm conditions
