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…

Abrupt transition between three and two-dimensional quantum turbulence
Nicolás P. Müller, Marc-Etienne Brachet, Alexandros Alexakis +1
We present numerical evidence of a critical-like transition in an out-of-equilibrium mean-field description of a quantum system. By numerically solving the Gross-Pitaevskii equatio…
