| Outline of Final Research Achievements |
Unlike the Earth, neutron stars seem to be huge quantum stars consisting mainly of superfluid neutrons. In the inner crust region where the density is sufficiently smaller than the nuclear density, neutron matter may show physical properties similar to ultracold atomic Fermi gases realized by laser cooling. We report on quantum simulation of pure neutron matter by using such atomic gases for the purpose of understanding the fundamental physical properties of dilute neutron-rich nuclear matter. As a main result, the thermodynamic properties, the short-range particle correlation, and the equation-of-state (EOS) of dilute pure neutron matter were determined. We also established a method to calculate the inner crust structure of neutron stars in order to obtain EOS of neutron star matter by using the EOS of pure neutron matter.
