| Research Abstract |
In quantum fluid such as superfluid liquid helium and ultracold atomic gas, vortices are quantized, i.e., strength of vortices are same for all vortices, and quantum turbulence can be realized as highly tangled state of quantized vortices. Quantized vortices are topological defects and have quite similar structure to other topological defects such as cosmic strings that are predicted to arise just after rapid cooling of universe and linear defects called disclinations in disturbed liquid crystal. In my work, I have succeeded to classify various kinds of quantum turbulence constructed by various kinds of topological defects to just two types of quantum turbulence with the Lorentz symmetry.
