TRANSPORT COEFFICIENTS OF A NORMAL FERMI LIQUID - APPLICATION TO LIQUID HE3

The transport coefficients of a normal Fermi liquid in the extreme low-temperature limit and the leading finite-temperature contributions to the transport coefficients are studied using the quasiparticle transport equation. The scattering amplitude for quasiparticles on the Fermi surface is expressed in terms of Landau parameters, using an approximation which takes into account s- and p-wave scattering; the calculated values of the transport coefficients in the extreme low-temperature limit for liquid He3 are shown to be in good agreement with the experimental values. Finite-temperature contributions to the transport coefficients are expressed in terms of the solution of the transport equation in the extreme low-temperature limit, and explicit calculations are performed for the case of liquid He3. Assuming Landau parameters with la 2 vanish, an estimate of the Landau parameter F1a for liquid He3 is obtained by comparing the theoretical and experimental values of the leading finite-temperature contributions to the transport coefficients. © 1969 The American Physical Society.
