{'sha1': '753cfe6e064a0b9db7dd49d92abd50abc4efed85', 'content': 'We present a model-independent description of low-density neutron matter\nbased on the virial expansion. The virial equation of state provides a\nbenchmark for all nuclear equations of state at densities and temperatures\nwhere the interparticle separation is large compared to the thermal wavelength.\nWe calculate the second virial coefficient directly from the nucleon-nucleon\nscattering phase shifts. Our results for the pressure, energy, entropy and the\nfree energy correctly include the physics of the large neutron-neutron\nscattering length. We find that, as in the universal regime, thermodynamic\nproperties of neutron matter scale over a wide range of temperatures, but with\na significantly reduced interaction coefficient compared to the unitary limit.', 'mimetype': 'text/plain', 'lang': 'en'}
