Homogeneous Nucleation in Liquid 3 He- 4 He Mixtures

Ring vortex destabilization in supersaturated 3 He - 4 He liquid mixtures at low temperatures

Thermodynamics of Liquid 'he- " He Mixtures

The osmotic pressure of 3He-4He solutions is shown to follow in a natural way from the separation of the specific heat in a quasiparticle contribution and a 4He-contribution. Expressions for important thermodynamic properties such as the chemical potentials, the internal energy, the entropy, specific heat, osmotic pressure, etc. are given for the case the quasiparticle gas can be treated as a n...

Surprising behavior of the superfluid fraction for 4 He and 3 He - 4 He mixtures in 18 . 5 nm channels

We have obtained the superfluid fraction of He and mixtures confined in channels 0.0185μm×1.08μm×∞ . We compare this with film data L×∞ ×∞, and data for channels 0.0483μm×3.0μm×∞ . The behavior of the data in the smallest channels is quite different from what one might expect for a planar film of a given thickness. The transition is shifted to a lower temperature than expected; and, the overall...

Simulations of oscillatory convection in 3 He – 4 He mixtures in moderate aspect ratio containers

sReceived 9 May 2004; accepted 28 March 2005; published online 26 May 2005d Simulations of He– He mixtures with negative separation ratios in two-dimensional containers with realistic boundary conditions and moderately large aspect ratio G are described. The system exhibits a large variety of states with complex time dependence including intermittent wave localization and chaotic “repeated tran...
