Spin Response of the Nuclear Pasta

Neutron-rich matter at subnuclear densities, such as the one present in the crust of a neutron star, displays fascinating complex structures known as pasta phases. Results for the two-body - spin-isospin dependent - correlation function in the nuclear pasta are presented. These results are obtained via semi-classical Monte-Carlo simulations with a Hamiltonian that incorporates a ``semi-classical'' short-range spin-dependent term that is added to simulate Pauli correlations.
