Weborder wave equation which will not be considered in this study; such an equation is a bit more complex than the one derived by Fay [8] to study the propagation of finite-amplitude, acoustic plane waves. Both Eq. (3) and Fay’s Eq. (4) include a third-order mixed derivative, i.e., the second term in the right-hand side of Eq. (3). WebWe describe the creation of localized density perturbations, or ion holes, in an ultracold neutral plasma in the hydrodynamic regime, and show that the holes propagate at the local ion acoustic wave speed. We also observe the process of hole splitting, which results from the formation of a density depletion initially at rest in the plasma.
