Matti Krusius is a researcher in the Low Temperature Laboratory of Aalto University, Finland. He has been studying extensively the helium- superfluids with a rotating refrigerator. Currently his work deals with superfluid dynamics in the zero temperature limit. The subject of the present viewpoint, the phase of superfluid helium-, has never been studied in rotation at these very low temperatures (in fact never below ). The dream is to make such exploration possible.
