# Mutual friction in superfluid $^{3}\mathrm{He}−\mathrm{B}$ in the low-temperature regime

J. T. Mäkinen, V. B. Eltsov
We measure the response of a rotating sample of superfluid $^{3}\mathrm{He}−\mathrm{B}$ to spin-down to rest in the zero-temperature limit. Deviations from perfect cylindrical symmetry in the flow environment cause the initial response to become turbulent. The remaining high polarization of vortices...
