Constraints on Skyrme Equations of State from Properties of Doubly Magic Nuclei and Ab-Initio Calculations of Low-Density Neutron Matter

Understand

We use properties of doubly-magic nuclei and ab-initio calculations of low-density neutron matter to constrain Skyrme equations of state for neutron-rich conditions.

• All of these properties are consistent with a Skyrme functional form and a neutron-matter equation of state that depends on three parameters.
• With a reasonable range for the neutron-matter effective mass, the values of the two other Skyrme parameters are well constrained.
• This leads to predictions for other quantities.
