    "abstract": "We study nuclear and neutron matter by combining chiral effective field\ntheory with non-perturbative lattice methods. In our approach nucleons and\npions are treated as point particles on a lattice. This allows us to probe\nlarger volumes, lower temperatures, and greater nuclear densities than in\nlattice QCD. The low energy interactions of these particles are governed by\nchiral effective theory and operator coefficients are determined by fitting to\nzero temperature few-body scattering data. Any dependence on the lattice\nspacing can be understood from the renormalization group and absorbed by\nrenormalizing operator coefficients. In this way we have a realistic simulation\nof many-body nuclear phenomena with no free parameters, a systematic expansion,\nand a clear theoretical connection to QCD. We present results for hot neutron\nmatter at temperatures 20 to 40 MeV and densities below twice nuclear matter\ndensity.",
