Intermittent Switching between Potential Flow and Turbulence in Superfluid Helium at mK Temperatures

Michael Niemetz, Hubert Kerscher, Wilfried Schoepe

Superfluid flow around an oscillating microsphere is investigated at temperatures down to 25 mK. Stable laminar flow below a critical velocity and turbulence at large drives are fo…
