Anomalous Damping of a Microelectromechanical Oscillator in Superfluid -B

P Zheng, WG Jiang, CS Barquist, Y Lee, HB Chan - Physical Review Letters, 2016 - APS
The mechanical resonance properties of a microelectromechanical oscillator with a gap of
1.25 μ m was studied in superfluid He 3-B at various pressures. The oscillator was driven in …

Superfluid surface states in a confined geometry probed by a microelectromechanical oscillator

WG Jiang, CS Barquist, K Gunther, Y Lee, HB Chan - Physical Review B, 2023 - APS
A microelectromechanical oscillator with a 0.73 µ m gap structure is employed to probe the
surface Andreev bound states in superfluid He 3-B. The surface specularity of the oscillator …
