Abstract

The superfluid density ρ s in the presence of persistent current(v n −v s ≠0) is investigated using the Doppler-shifted fourth-sound technique. In the vortex-free Landau state, ρ s remains constant within our experimental resolution of two parts in 10 5 . This is not inconsistent with a theoretical prediction by Khalatnikov. Where vortices are present outside the Landau region, a fractional change in ρ s becomes as large as 1.2%, depending on rotation velocity and temperature, and shows a relatively complex hysteresis behavior.
