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)…
Temperature Dependence of Viscosity in Normal Fluid He Below 800mK Determined by a Micro-electro-mechanical Oscillator
M. Gonzalez, W. G. Jiang, P. Zheng +3
A micro-electro-mechanical system vibrating in its shear mode was used to study the viscosity of normal liquid He from 20mK to 770mK at 3bar, 21bar, and 29bar. The damping coef…
Knudsen-to-Hydrodynamic Crossover in Liquid 3He in a High-Porosity Aerogel
H. Takeuchi, S. Higashitani, K. Nagai +6
We present a combined experimental and theoretical study of the drag force acting on a high porosity aerogel immersed in liquid He and its effect on sound propagation. The dr…
Ultrasound attenuation and a P-B-T phase diagram of superfluid 3He in 98% aerogel
B. H. Moon, N. Masuhara, P. Bhupathi +4
Longitudinal sound attenuation measurements in superfluid 3He in 98% aerogel were conducted at pressures between 14 and 33 bar and in magnetic fields up to 4.44 kG. The temperature…
The A-B Transition of Superfluid Helium-3 in Aerogel and the Effect of Anisotropic Scattering
C. L. Vicente, H. C. Choi, J. S. Xia +3
We report the results of high frequency acoustic shear impedance measurement on superfluid helium-3 confined in 98% porosity silica aerogel. Using 8.69 MHz continuous wave excitati…
