Turbulence in quantum fluids

This paper reviews briefly the recent important developments in the physics of quantum turbulence (QT) in superfluid helium and atomic Bose-Einstein condensates (BECs). After giving the basics of quantum hydrodynamics, we discuss energy spectrum, QT created by vibrating structures, and visualization among the topics on superfluid helium. For atomic BECs we review three-dimensional QT, two-component BECs. and spin turbulence in spinor BECs. The last part is devoted to some perspectives of this issue.
