Liquid 3He in Aerogel: Crossover from Drude’s to Hagen-Poiseuille’s Law
نویسندگان
چکیده
Charge flow in metals and mass flow in a neutral Fermi liquid show distinct profiles and are governed by different conservation properties. The connections between these two aspects of flow become apparent when we study the viscous flow of normal liquid 3He in the presence of aerogel. While the thermal flow is trivially affected, we predict that the resistance to mass flow shows a crossover from Drude’s to Hagen-Poiseuille’s law with varying temperature and low aerogel concentration. This crossover should be observable in dc-flow experiments. [S0031-9007(98)07528-0]

Knudsen-to-hydrodynamic crossover in liquid 3He in a high-porosity aerogel.
We present a combined experimental and theoretical study of the drag force acting on a high porosity aerogel immersed in liquid (3)He and its effect on sound propagation. The drag force is characterized by the Knudsen number, which is defined as the ratio of the quasiparticle mean free path to the radius of an aerogel strand. Evidence of the Knudsen-hydrodynamic crossover is clearly demonstrate...
متن کاملSound Propagation and Transport Properties of Liquid 3 He in
Superfluid 3He confined in aerogel offers a unique chance to study the effects of a short mean free path on the properties of a well defined superfluid Fermi liquid with anisotropic pairing. Transport coefficients and collective excitations, e.g. longitudinal sound, are expected to react sensitively to a short mean free path and to offer the possibility for testing recently developed models for...
متن کاملHeat capacity of 3He in aerogel.
The heat capacity of pure 3He in low density aerogel is measured at 22.5 bars. The superfluid response is simultaneously monitored with a torsional oscillator. A slightly rounded heat capacity peak, 65 microK in width, is observed at the 3He-aerogel superfluid transition, T(ca). Subtracting the bulk 3He contribution, the heat capacity shows a Fermi-liquid form above T(ca). We can fit the heat c...
متن کاملAcoustic Spectroscopy of Superfluid 3He in Aerogel
N. Mulders Department of Physics and Astronomy, University of Delaware, 223 Sharp Laboratory, Newark, Delaware 19716 (Received 21 December 1998) Liquid 3He in 98%-porous aerogel simultaneously possesses properties of a disordered p-wave superfluid and an elastic solid. We have observed two sound modes of superfluid 3He in aerogel. The first (fast) sound is a compression wave, and the second (sl...
متن کاملMagnetic phase transition in a nanonetwork of solid 3He in aerogel.
When immersed in liquid 3He, the nanometer strands of aerogel are coated with a thin layer of solid 3He, forming a network of irregular nanotubes. Owing to its high purity and weak interactions, this system is ideal for studying fundamental processes. We report the first experiments on solid 3He in aerogel at ultralow temperatures, cooled by direct adiabatic demagnetization. Simultaneous nuclea...
