Charged-surface instability development in liquid helium: An exact solution

NM Zubarev - Journal of Experimental and Theoretical Physics …, 2000 - Springer
The nonlinear dynamics of charged-surface instability development is investigated for liquid
helium far above the critical point. It is found that, if the surface charge completely screens …
