ABSTRACT:

Highly dense nuclear matter of the type found in neutron stars was simulated in numerical code written and subsequently amended by Dr. Fridolin Weber’s research group. Equations of state for infinite nuclear matter are produced for different relative nucleon number densities. Comparisons to symmetric nuclear matter are shown as a baseline. The change in behavior of the system based on these relative densities is obtained with the calculation of the properties of various particles within the simulated nucleonic matter. In order to obtain behavior consistent with neutron star densities, the code finds the mass operator, Σv,s,0, which is applied separately to both nucleons, using a root-finding technique that currently converges at densities up to near 7 times nuclear saturation (.16 Nfm3 ). The slope of the asymmetry energy will be checked in these extremely high nucleon density environments, and the compressibility is found using the equation of state at particular densities to compare against established theory. The calculations are performed using spectral function representation in the complex energy plane in a self-consistent manner, with different ratios of nucleons present.
