Bosonization of the Hamiltonian and the density-density correlation function level of the Gaussian approximation the problem of deriving the bosonic representation of the Hamiltonian is closely related to the problem of calculating the density-density correlation function within the RPA. We develop a general formalism for obtaining corrections to the Gaussian approximation,

However, Luttinger liquid behavior in three dimensions can be due to quasi-one-dimensional anisotropy in the electronic band structure or in the phonon frequencies.
