Measurement of Wall Relaxation Times of Polarized Helium-3 in Bulk Liquid Helium-4 for the Neutron Electric Dipole Moment Experiment
The relaxation rates extrapolated from the observed values of Pd for d-TPB, coated Torlon, and coated BeCu in the nEDM apparatus were found to be consistent with design goals.

Many-Body Effects in the Thermodynamic Properties of Fermi Liquids and the Electron-Phonon System and in the Excitation Spectrum of Liquid Helium-4
… effects in the thermodynamic properties of Fermi liquids and of the electron-phonon system. Using normal liquid ('3)He as an example, I show that the T('3)lnT corrections due to spin fluctuations account for the finite temperature corrections to the leading term in the specific heat. I also …

Quantum turbulence generated by moving grids
… of frequency and similar to what was measured in liquid helium-4 in its normal phase. We also present measurements of the inertial drag coefficient for grid turbulence, which is significantly reduced by turbulence produced in both superfluid and normal fluid 4He. To produce (approximate) …

Cooling an electron gas using quantum dot based electronic refrigeration
… are made by cooling the sample to 1.5 K with liquid Helium-4, to 300 mK with liquid Helium-3, or even down to a few mK using a dilution refrigerator. However, at lower temperatures the electron gas becomes increasingly decoupled from the lattice in which it resides. Below ~ 1 K the coupling …
