We re-examine the calculation of the transverse spin-diffusion coefficient in a dilute degenerate spin-polarized Fermi gas, for the case of s-wave scattering. The special feature of this limit is that the dependence of the spin diffusion coefficient on temperature and field can be calculated explicitly with no further approximations. This exact solution uncovers a novel intermediate behaviour between the high field spin-rotation dominated regime in which D⊥ ∝ H−2, D∥ ∝ T−2, and the low-field…

Theory of low temperature kinetic phenomena in metals without inversion center is developed. Kinetic properties of a metal without inversion center are described by four kinetic equations for the
Polarization Induced Spin Wave Damping in Spin Polarized Liquid 3He–4He
Abstract We have measured the temperature and polarization dependence of Silin spin wave spectra in a saturated 3He–4He mixture with a concentration of 9.4% at a pressure of 8 bars. The mixture has
Derivation of Transverse Spin-Wave Dynamics from a Kinetic Equation in a Rotating Reference Frame

Zero-temperature attenuation and transverse spin dynamics in fermi liquids. III. Low spin polarizations
This is the third in a series of papers on microscopic theory of transverse dynamics in spin-polarized Fermi liquids. In the lowest order in polarization our exact general theory of Ref. 1 reproduces
Spin diffusion in dilute, polarized 3He-4He solutions
Spin dynamics for arbitrarily polarized and very dilute solutions of 3He in liquid 4He are described. We began at a very fundamental level by deriving a kinetic equation for arbitrarily polarized
Transverse spin dynamics of a spin-polarized Fermi liquid
A microscopic derivation of the equations of transverse spin dynamics of a spin-polarized Fermi liquid at zero temperature is given in the leading-order approximation in the frequencies and wave
Statistical quasiparticles in transverse dynamics of gases.
It is demonstrated that the diagrammatic kinetic equation for transverse processes can be formulated as a simpler, but completely equivalent equation in terms of "statistical quasiparticles", which provides a somewhat unexpected interpretation for zero-temperature dissipative processes.
Exact transport properties of degenerate, weakly interacting, and spin-polarized fermions
Exact results for the transport coefficients of a highly degenerate spin-polarized Fermi system are presented. The case of weakly interacting particles, such as dilute3He in4He or D ↓, is treated.
Transverse dynamics and relaxation in spin-polarized or two-level Fermi systems.
A microscopic theory is proposed for transverse dynamics and zero-temperature attenuation in polarized Fermi liquids and a framework for a generalized nonlocal Landau theory is established.
Spin waves and spin diffusion in Fermi liquids: Bounds on effective diffusion coefficients.
Upper and lower bounds on the effective diffusion coefficient resulting from spin-wave phenomena are determined, which are accurate in the whole Fermi-liquid regime.
Observation of field-induced spin-current relaxation in a Fermi liquid.
The erect measured is more pronounced than suggested by scaling a dilute-gas theory result by a Fermi-liquid factor, and is less than measured in earlier experiments at lower B 0.
