Little Big Bangs in Helium-Three
With an eye toward the interpretation of so-called ‘cosmological’ experiments performed on the low temperature phases of 3He, in which regions of the superfluid are destroyed by local heating with neutron radiation, we have studied the properties of degenerate Fermi systems under certain extreme …

Thermal conductivity of liquid helium three
We have measured the thermal conductivity of liquid He3 at low pressure from O. 055 0 K to O. 47 o K, at 99.8 psi from O. 0550 K to O. 750 K and at 396.8 psi from O. 0550 K to O. 87 o K. At all pressures and at sufficiently low temperatures the thermal conductivity increases with decreasing …

Effective interactions, transport properties, and elementary excitations in helium three-helium four mixtures
… in 3He-4He mixtures is calculated by including three physical effects: (i) the change in the particle density, (ii) mode-mode coupling iv between 4He and 3He density fluctuation, (iii) direct scattering of 4He rotons against 3He quasiparticles. By using the theory developed by Aldrich and Pines, …

Application of compressional cooling to the study of nuclear ordering in solid helium three
"A powerful cooling technique for He3 has been used to observe ordering of the nuclear spins in solid He3 He3 atoms in the solid are localized at lattice sites. Interactions between neighboring atoms, due to zero point motion, are relatively small until temperatures in the low I millidegree Kelvin …

Spin-lattice relaxation of trivalent praseodymium, terbium, and erbium in anhydrous lanthanum trichloride: Temperature and magnetic field dependence
… experiments were attained through the use of a helium-three cryostat. The construction of this cryostat and the associated ESR pulse spectrometer are described in some detail.
