lntedacial Tension Near the Tricritical Point in 3He--4He Mixtures
نویسندگان
چکیده
The same relationship holds for the interfacial tension o-i at the consolute critical point (the critical point for phase separation) of a binary fluid mixture. Up to now no rigorous theory links the interfacial tension to properties of the bulk system. However, a phenomenological approach which should be valid in the vicinity of the critical point has been developed by Fisk and Widom. 2 According to their theory, the interfacial tension for a binary mixture is given by

Critical casimir effect and wetting by helium mixtures.
We have measured the contact angle of the interface of phase-separated 3He-4He mixtures against a sapphire window. We have found that this angle is finite and does not tend to zero when the temperature approaches T(t), the temperature of the tricritical point. On the contrary, it increases with temperature. This behavior is a remarkable exception to what is generally observed near critical poin...
متن کاملDissipation mechanisms near the superfluid 3He transition in aerogel.
We have investigated the dissipation (Q-1) using the torsion pendulum technique for pure 3He and 3He-4He mixtures in silica aerogel near the 3He superfluid transition (T(c)) in aerogel. With pure 3He the Q-1 decreases at the onset of superfluidity. When phase separated 3He-4He mixtures are introduced into the aerogel, the Q-1 does not decrease as rapidly and eventually increases for the highest...
متن کاملA simple model describing 3He-4He mixtures near a wall
2014 We describe the superfluid ordering taking place near a wall in 3He-4He mixtures by means of a semi-infinite version of the Blume-Emery-Griffiths model. A renormalization group analysis of the simplest version of this model yields a phase diagram which compares satisfactorily with available experimental data. J.

متن کاملSound propagation in coexistent Bose and Fermi superfluids in aerogel.
We report the first observation of longitudinal sound propagation in three dimensionally distributed Bose and Fermi superfluids in an acoustic investigation of phase separated 3He-4He mixtures confined to aerogel. At mK temperatures, this inhomogeneous system exhibits simultaneous 3He and 4He superfluidity leading to two "slow modes" along with the conventional sound mode. We also infer the sup...
متن کاملSimulations of localized States of stationary convection in 3He-4He mixtures.
Simulations of convection in 3He-4He mixtures with a negative separation ratio in two-dimensional containers with realistic boundary conditions and moderately large aspect ratio reveal, at supercritical Rayleigh numbers, the existence of "convectons," i.e., localized states of stationary convection, separated by regions of no convection. The origin and properties of these states are described.
