Non-equilibrium steady state of the superfluid mixtures of helium isotopes at classical temperatures
نویسنده
چکیده
The size effect in the gas of impuritons of the superfluid mixtures of helium isotopes is investigated by taking into consideration the contribution of thermal excitations. The solution is obtained for the set of kinetic equations describing a non-equilibrium state of the phonon-impuriton system of a superfluid mixture situated in the volume filled with the macroparticles. It allows to find the condition describing a steady, thermodynamically non-equilibrium state of 3He −4 He mixture in confined geometry. The Knudsen effect in the gas of impuritons of a superfluid mixture is investigated by taking into account the contribution of phonons. A model for the collision operator has been proposed to analyze the exact results in the context of the concrete physical situations. An experiment for the investigation of the Knudsen effect in a superfluid mixture of helium isotopes is proposed.

متن کاملShell Models of Superfluid Turbulence
Superfluid helium consists of two inter-penetrating fluids, a viscous normal fluid and an inviscid superfluid, coupled by a mutual friction. We develop a two-fluid shell model to study superfluid turbulence and investigate the energy spectra and the balance of fluxes between the two fluids in a steady state. At sufficiently low temperatures a ’bottle-neck’ develops at high wavenumbers suggestin...
متن کاملSupersolid and the Non-uniform Condensate
We construct a model of non-uniform condensate having a spatially modulated complex order parameter that makes it kinematically an x-ray solid, i.e., a real mass density wave, but one admitting an associated superfluid flow. Intrinsic to this state is a non-classical translational inertia which we derive for the case of a potential flow. Connection to the non-classical rotational inertia observ...
متن کاملPair Correlations in Superfluid Helium 3
In 1996 Lee, Osheroff and Richardson received the Nobel Prize for their 1971 discovery of superfluid helium 3 – a discovery which opened the door to the most fascinating system known in condensed matter physics. The superfluid phases of helium 3, originating from pair condensation of helium 3 atoms, turned out to be the ideal test-system for many fundamental concepts of modern physics, such as ...
متن کاملAccelerated path integral methods for atomistic simulations at ultra-low temperatures.
Path integral methods provide a rigorous and systematically convergent framework to include the quantum mechanical nature of atomic nuclei in the evaluation of the equilibrium properties of molecules, liquids, or solids at finite temperature. Such nuclear quantum effects are often significant for light nuclei already at room temperature, but become crucial at cryogenic temperatures such as thos...
