摘要：

The Quantum Hydrodynamic Model is used to describe the dynamics of a quantum plasma. In this framework we relax the standard assumption of irrotational velocity field by including a natural solenoidal component. Using a Madelung transformation, it is shown that the fluid equations can be embedded in a non-linear Schrodinger equation in the presence of a self-consistent electrostatic potential and a pseudo-magnetic potential obeying an induction-like equation. This novel system is used to investigate the quantum fluid turbulence of a two-dimensional quantum plasma. While qualitative phenomena, like the dual cascade, are confirmed numerically, it is found that the inclusion of rotational effects changes significantly the evolution of the turbulence spectrum.
