Query: Mesoscopic dynamics of fermionic cold atoms ---Quantitative analysis of
  transport coefficients and relaxation times---   We give a quantitative analysis of the dynamical properties of fermionic cold
atomic gases in normal phase, such as the shear viscosity, heat conductivity,
and viscous relaxation times, using the novel microscopic expressions derived
by the renormalization group (RG) method, where the Boltzmann equation is
faithfully solved to extract the hydrodynamics without recourse to any ansatz.
In particular, we examine the quantum statistical effects, temperature
dependence, and scattering-length dependence of the transport coefficients and
the viscous relaxation times. The numerical calculation shows that the relation
$\tau_\pi=\eta/P$, which is derived in the relaxation-time approximation (RTA)
and is used in most of the literature, turns out to be satisfied quite well,
while the similar relation for the viscous relaxation time $\tau_J$ of the heat
conductivity is satisfied only approximately with a considerable error.
