چکیده

We present the first measurements of the thermal conductivity of spin-polarized normal liquid 3He. Using the rapid melting technique to produce nuclear polarizations up to 0.7, and a vibrating wire both as a heater and a thermometer, we show that, unlike the viscosity, the conductivity increases much less than predicted for s-wave scattering. We suggest that this might be due to a small probability for head-on collisions between quasiparticles.

Thermodynamic properties of polarized liquid 3He along different isentropic paths

The dependence of some thermodynamic properties of spin-polarized liquid 3He such as velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. The Lennard-Jones potential has been used in our calculations. It has been found that for higher values of entropy, the spin polarization has greate...

Temperature Increase of Highly-Polarized Fermi Liquids in Spin-Echo Experiments

We show that there are restrictions on the maximum tipping angle that can be used without significantly raising the temperature of the 3He distribution in high B/T spin-echo experiments with pure liquid 3He and 3He-4He solutions. The temperature increase occurs during the diffusion process as quasiparticles in mixed-spin states are scattered and converted into thermal excitations at the spin-up...

Low-temperature spin diffusion in a spin-polarized Fermi gas.

We present a finite temperature calculation of the transverse spin-diffusion coefficient, D⊥, in a dilute degenerate Fermi gas in the presence of a small external magnetic field, H. While the longitudinal diffusion coefficient displays the conventional low-temperature Fermi-liquid behavior, D‖ ∝ T−2, the corresponding results for D⊥ show three separate regimes: (a) D⊥ ∼ H−2 for T ≪ H; (b) D⊥ ∼ ...

Effective Neutron Targets

Because of the lack of a free neutron target, deuterium targets have been used extensively in studying the neutron structure. The unique spin structure of the 3He ground state wave function and the recent developments in laser technologies made polarized 3He targets widely used in many experiments from neutron electromagnetic form factor studies to nucleon spin structure function measurements a...

Spin-polarized 3He : liquid gas equilibrium

We study the effects of nuclear polarization M on the liquid-gas equilibrium phase diagram of 3He, in situations where the saturating vapour pressure increases or decreases as a function of M, and where a metamagnetic instability may occur in the liquid phase. Numerical predictions are given within the frame of a phenomenological model with parameters fitted to reproduce accurately the saturati...
