Abstract
A method based on Landau's Fermi-fluid theory is presented for calculating the temperature-dependent viscosity η and thermal conductivity κ of a Fermi fluid. It is argued that both O(T) and O(T2 ln T) terms appear in the temperature series expansions for ηT2 and κT. Exact expressions for the zero-temperature limit of ηT2 and κT are derived for the dilute hard-sphere Fermi gas (DHSFG). The leading finite-temperature corrections to these quantities due to the s dependence of the quasiparticle scattering amplitude are also derived for the DHFSG (s is a dimensionless ratio of energy transfer to momentum transfer). The results are compared with previous expressions of Emery and of Dy and Pethick; some discrepancies are noted and discussed.
