| Outline of Final Research Achievements |
To study for the flow of superfluid helium four in nanopore, we measured vibrating wire with a nanopore plate response.
Below superfluid transition temperature, resonance curves show anomalous behavior when the velocity is high. This behavior are not shown in the experiment with no pore, so the superfluid flow in the pore become unusual. At the relatively low velocity, the superfluid flow in nanopore behavior can be explained by thermal activated quantum vortex model, and at high velocity region, quantum turbulence should be occurred.
