Current research interests:
I am currently interested in quantum turbulence and vortex dynamics in helium superfluids.
Compared with classical fluids, vortices in helium superfluids (in the superfluid component)
are very stable and have a fixed circulation. A small vortex core size makes it possible
to use the vortex filament model and Biot-Savart equation to determine the vortex dynamics.
My numerical research is connected to the experiments done especially by the
However, they also relate to experiments conducted, for example, in Manchester, Lancaster, and Osaka.
Some active projects:
For more information about some other projects I refer to the
helium theory page of
the Low Temperature Laboratory.
- Conservation laws for energy, momentum, helicity, etc and their effect on the vortex dynamics.
- Vortex reconnections.
- Counterflow turbulence.
- Decay of quantum turbulence and the role of Kelvin-waves, especially in the zero temperature limit.
- Spin-down of the superfluid component after a sudden stop of rotation.
- Twisted vortex state and propagating vortex front.
Spin-down of cubic container at T = 0.22Tc in superfluid 3He-B.
