Query: Energy absorption spectroscopy of unitary Fermi gases in a uniform
  potential   We propose to use the energy absorption spectroscopy to measure the kinetic
coefficients of unitary Fermi gases in a uniform potential. We show that in our
scheme, the energy absorption spectrum is proportional to the dynamic structure
factor of the system. The profile of the spectrum depends on the shear
viscosity $\eta$, the thermal conductivity $\kappa$ and the superfluid bulk
viscosity $\xi_3$. We show that extraction of these coefficients from the
spectrum is achievable in present experiments.
