Spin Susceptibility in Neutron Matter from Quantum Monte Carlo Calculations

Abstract

The spin susceptibility in pure neutron matter is computed from auxiliary field diffusion Monte Carlo calculations over a wide range of densities. The calculations are performed for different spin asymmetries, while using twist-averaged boundary conditions to reduce finite-size effects. The employed nuclear interactions include both the phenomenological Argonne AV8${}^{\prime }$+UIX potential and local interactions that are derived from chiral effective field theory up to next-to-next-to-leading order.
