Low energy density correlation function of the degenerate unitary Fermi gas from epsilon expansion

Using $ε$ expansion proposed in \cite{Nishida:2006br} we calculate density correlation function of the degenerate Fermi gas at infinite scattering length to next-to-leading order in $ε$ for excitation energies below quasi particle threshold. An expression for the low energy dynamic structure function is derived.
