The Superfluid Pairing Gap of a Neutron Star
Abstract
It is very important to investigate the properties of the neutron superfluid that exists inside neutron stars. For example, it is known that the cooling curves of the stars strongly depend on the superfluid pairing gap. The theoretical study is very challenging due to the complexity of the physical system in such extreme conditions. Cold atoms can help us shed light into physical mechanisms within the interior of the star; their unique flexibility, in fact, makes these systems laboratories to explore many-body physics, with applications in condensed matter physics, nuclear physics, and nuclear astrophysics. We perform extensive Quantum Monte Carlo calculations of the pairing gap for a cold atomic Fermi system. We present preliminary results and we discuss their significance for the cooling curves of neutron stars.
