ABSTRACT
An expansion of the thermodynamic potential in powers of the order parameter of the superfluid phase transition is found for liquid [sup 3]He in an aerogel at T=0. The discontinuity in the compressibility (sound velocity), which is the analog of the discontinuity in the specific heat for second-order temperature phase transitions, is calculated. The magnitude of the critical quantum fluctuations (zero-point vibrations) of the order parameter is estimated. © 1997 American Institute of Physics.

    We derive an exact semiclassical expression for the second inertial parameter B for superfluid and normal phases. Interpolation between these limiting values shows that the function B(I) changes sign at the spin I[sub c] that is critical for the rotational spectrum. The quantity B proves to be a...

    Superfluid He shares with superconductors a transition into a low temperature state where the order parameter is a wave function. For the low temperature superconductors, which have a large zero temperature correlation length, this results in well known Josephson effects reflecting the overlap...

    It is shown that paraazoxyanisole has four solid-crystal forms. The heats and temperatures of melting and transition are related by the following five equations: Q[sub m](IV) = Q[sub m](II); Q[sub m](IV) = Q[sub m](I) + Q[sub m](III); T[sub m](IV) = T[sub m](III); T[sub tr](II-III) = T[sub...
