Multimode probing of superfluid by tuning forks
A. Guthrie, R. P. Haley, A. Jennings +9
Flexural mode vibrations of miniature piezoelectric tuning forks (TF) are known to be highly sensitive to superfluid excitations and quantum turbulence in and $\mat…

Detecting the "phonon wind" in superfluid by a nanomechanical resonator
A. M. Guenault, A. Guthrie, R. P. Haley +8
Nanoscale mechanical resonators are widely utilized to provide high sensitivity force detectors. Here we demonstrate that such high quality factor resonators immersed in superfluid…

Driving nanomechanical resonators by phonon flux in superfluid \(\mathbf{^4He}\)
A. M. Guénault, A. Guthrie, R. P. Haley +10
We report on nanomechanical resonators with very high-quality factors operated as mechanical probes in liquid helium \(^4\mathrm{He}\), with special attention to the superfluid reg…
