  2. Phase separation in solid mixtures of helium-3 and helium-4

    Ehrlich, Steven Neil2011

    Phase separation temperatures have been determined in bee 3He-4He mixtures as a function of 3He concentration and melting pressure from measurements of changes in the x-ray lattice parameter and peak shape. A new rigid tail dilution refrigerator cryostat is used to study 3 He-4He crystals with 3He …

    … detec- tors have made this possible. The helium resonance fluorescence LiDAR has the capability to probe the metastable helium content in the thermosphere and exosphere (within 250 km-750 km), where helium (23S) is most abundant. Strategies have been employed to increase the output power …

  5. Effective interactions, transport properties, and elementary excitations in helium three-helium four mixtures

    Hsu, Wei-Chan2011

    A unified theory of effective interaction, elementary excitations, transport properties, and possible superfluidity of 3He-4He mixtures has been developed. The basic approach is patterned after that of Aldrich and Pines (AP) for pure 4He and 3He , 1n which the consequence of the strong interactions …

  9. Superglass Dynamics Of Solid Helium

    Pratt, Ethan2010

    Although solid 4 He may be a supersolid, it also exhibits many phenomena unexpected in that context. In order to measure the finely resolved time-dependent inertial response of this exotic quantum material, we constructed a vibrationallyisolated millikelvin cryostat with automated data acquisition …

  10. Superfluid helium on solid hydrogen

    Chen, Ming-TangUniversity of Illinois at Urbana-Champaign2011

    We measure the third sound velocity of superfluid helium films as functions of temperature and film coverage on H$\sb2,$ D$\sb2,$ and Ar substrates. A new phase of superfluid is discovered on the weak-binding H$\sb2$ substrate. We observe, in addition to third sound, a new surface mode of wave …
