Dynamics of pinned quantized vortices in superfluid He in a microelectromechanical oscillator
Tomo Nakagawa, Makoto Tsubota, Keegan Gunther +1
We numerically studied the vortex dynamics at zero temperature in superfluid He confined between two parallel rough solid boundaries, one of which oscillates in a shear mode. T…
Superfluid He-B Surface States in a Confined Geometry Probed by a Microelectromechanical Oscillator
W. G. Jiang, C. S. Barquist, K. Gunther +2
A microelectromechanical oscillator with a 0.73 m gap structure is employed to probe the surface Andreev bound states in superfluid He-B. The surface specularity of the osci…
Signatures and Detection Prospects for sub-GeV Dark Matter with Superfluid Helium
Yining You, Jordan Smolinsky, Wei Xue +4
We explore the possibility of using superfluid helium for direct detection of sub-GeV dark matter (DM). We discuss the relevant phenomenology resulting from the scattering of an in…
Determining the source of phase noise: Response of a driven Duffing oscillator to low-frequency damping and resonance frequency fluctuations
C. S. Barquist, W. G. Jiang, K. Gunther +1
We present an analytical calculation of the response of a driven Duffing oscillator to low-frequency fluctuations in the resonance frequency and damping. We find that fluctuations…
Damping of a micro-electromechanical oscillator in turbulent superfluid He: A novel probe of quantized vorticity in the ultra-low temperature regime
C. S. Barquist, W. G. Jiang, K. Gunther +3
We report a comprehensive investigation of the effects of quantum turbulence and quantized vorticity in superfluid He on the motion of a micro-electromechanical systems (MEMS)…
