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

arXiv:0804.2919 · doi:10.1103/PhysRevA.81.043617

Abstract

Using 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 for excitation energies below quasi particle threshold. An expression for the low energy dynamic structure function is derived.
