Pressure and Size Dependence of Roton Emission and Vortex Creation by Moving Objects in He~II in Limit: Generalized Nonlocal Gross-Pitaevskii Model
Nicolás Pablo Müller, Ladislav Skrbek, Yuri A. Sergeev +1
In the framework of generalized, nonlocal Gross-Pitaevskii (GP) model, we study numerically the pressure- and size-dependent mechanisms of roton emission and vortex nucleation by o…

Experimental and theoretical evidence of universality in superfluid vortex reconnections
Piotr Z. Stasiak, Yiming Xing, Yousef Alihosseini +5
The minimum separation between reconnecting vortices in fluids and superfluids obeys a universal scaling law with respect to time. The pre-reconnection and the post-reconnection pr…
