    "abstract": "We start from a low-energy effective field theory for interacting fermions on\nthe lattice and expand in the hopping parameter to derive the nearest-neighbor\ninteractions for a lattice gas model. In this model the renormalization of\ncouplings for different lattice spacings is inherited from the effective field\ntheory, systematic errors can be estimated a priori, and the breakdown of the\nlattice gas model description at low temperatures can be understood\nquantitatively. We apply the lattice gas method to neutron matter and compare\nwith results from a recent quantum simulation.",
