    "abstract": "The properties of high-density nuclear and neutron matter are studied using a\nrelativistic mean-field approximation to the nuclear matter energy functional.\nBased on ideas of effective field theory, nonlinear interactions between the\nfields are introduced to parametrize the density dependence of the energy\nfunctional. Various types of nonlinearities involving scalar-isoscalar\n($\\sigma$), vector-isoscalar ($\\omega$), and vector-isovector ($\\rho$) fields\nare studied. After calibrating the model parameters at equilibrium nuclear\nmatter density, the model and parameter dependence of the resulting equation of\nstate is examined in the neutron-rich and high-density regime. It is possible\nto build different models that reproduce the same observed properties at normal\nnuclear densities, but which yield maximum neutron star masses that differ by\nmore than one solar mass. Implications for the existence of kaon condensates or\nquark cores in neutron stars are discussed.",
