ROSE: A reduced-order scattering emulator for optical models
Daniel Odell, Pablo Giuliani, Kyle Beyer +6
A new generation of phenomenological optical potentials requires robust calibration and uncertainty quantification, motivating the use of Bayesian statistical methods. These Bayesi…
Threefold Reduction in Thermal Conductivity of Vycor Glass Due to Adsorption of Liquid 4He
Zhigang Cheng, Moses H. W. Chan
We report thermal conductivity measurements of porous Vycor glass when it is empty and when the pores are filled with helium between 0.06 and 0.5 K. The filling of liquid 3He and l…
He Crystal Quality and Rotational Response in a Transparent Torsional Oscillator
A. D. Fefferman, X. Rojas, A. Haziot +3
We have studied natural purity He single crystals and polycrystals between 10 and 600 mK using a torsional oscillator with a 2 cm rigid cell made of sapphire with a smo…
Influence of Ortho-H2 Clusters on the Mechanical Properties of Solid Para-H2
A. C. Clark, Z. G. Cheng, M. Bowne +2
The quantum diffusion of ortho-H2 impurities in solid para-H2 has been investigated with a torsional oscillator technique. The unclustering dynamics of agglomerated impurities with…
Supersolid behavior in confined geometry
J. T. West, X. Lin, Z. G. Cheng +1
We have carried out torsional oscillator (TO) and heat capacity (HC) measurements on solid 4He samples grown within a geometry which restricts the helium to thin (150 um) cylindric…
Thermal History of Solid 4He Under Oscillation
A. C. Clark, J. D. Maynard, M. H. W. Chan
We have studied the thermal history of the resonant frequency of a torsional oscillator containing solid 4He. We find that the magnitude of the frequency shift that occurs below 10…
