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…

Spherically symmetric counterflow turbulence in open geometry
Tomáš Dunca, Filip Novotný, Marek TalÃÅ +4
We report preliminary results on spherical thermal counterflow generated by a small central heater in an open geometry, an open bath of superfluid He~II, as closed-cell experiments…
