“…To check the validity of the assumptions made we are to compare the formula (42) with experimental data. Here we make use of experiments 37 where T λ was measured in 3 He-4 He mixtures under pressure at several values of x. We transform these results into T λ (n) dependence using equations of state for different x at T = 1.5 K, which hardly can introduce any significant error.…”

We further analyze the recently proposed criterion, according to which a superfluid transition occurs whenever the r.m.s. displacement of a particle from its initial position in imaginary time reaches a certain fraction of the interparticle distance. The critical temperature T λ is expressed in terms of the single particle mobility. Within the Drude approximation for the mobility T λ is determined by the friction coefficient (or by the viscosity for dense liquids). To check the validity of the criterion the resulting formula is applied to non-ideal Bose gas, to liquid helium and to 3 He-4 He mixtures. A reasonable qualitative agreement with available experiments is obtained in all cases. In the case of the Bose gas the present approach results also in an upper bound on the peak value of T λ /T 0 λ , where T 0 λ is the critical temperature for the ideal gas.

Nucleation of transitions in liquid 3He-4He mixtures

We present a complete set of data describing the nucleation both of superfluidity and phase separation at container walls in liquid 3He-aHe mixtures. The appearance of superfluidity and the growth of phase-separated films are measured locally at the walls. A theoretical interpretation is given, important results of which are that the phase separation and superfluid transitions become uncoupled when the transitions are localized near the walls and that quantum fluctuations most probably strongly affect the nature of the superfluid nucleation transition at low temperature. Further, comparison of our results with data for transitions in pure 4He films demonstrates that a universality principle governs the transitions in both systems.
