A low-energy effective Hamiltonian for Landau quasiparticles: II. Application to the contact Fermi gas
The paper applies a new renormalization scheme to construct a quantized theory of Fermi liquids using an effective Hamiltonian for an atomic Fermi gas with contact interactions. It derives renormalized parameters and corrections to static properties, such as the critical temperature, and demonstrates preexponential corrections to zero sound velocity in the collisionless regime.
