160. Neutron star properties from semiclassical methods in nuclear physics

Semiclassical methods

Talk

Semiclassical methods in nuclear physics are a very good tool to study the behavior and composition of neutron stars. Using the Vlasov equation, the neutron star crust-core transition will be discussed, also in the presence of a strong magnetic field as expected inside magnetars. The description of the inner crust within a Thomas Fermi approach will be presented.

Semiclassical methods

Talk

A novel Thomas-Fermi (TF) approach to inhomogeneous superfluid Fermi-systems is presented and shown that it works well also in cases where the Local Density Approximation (LDA) breaks down. The novelty lies in the fact that the semiclassical approximation is applied to the pairing matrix elements not implying a local version of the chemical potential as with LDA. Applications will be given to...
