| Research Abstract |
We studied theoretically quantum hydrodynamics in superfluid helium and atomic Bose-Einstein condensates(BECs). Hydrodynamics in these systems is dominated by quantum mechanical effects, and a quantized vortex appears as an element of vorticity. In superfluid helium, we succeeded for the first time in making statistically steady states in thermal counterflow and the characteristic velocity distribution. In atomic BECs, we revealed quantum turbulence and Kelvin-Helmholtz instability in two-component BECs, and spin turbulence in spinor BECs
