In-medium nucleons and nucleonic systems: Infinite nuclear matter

In the present work we discuss the modifications of infinite nuclear matter properties. The modifications are performed in the framework of the in-medium modified Skyrme model. The model is developed to study the properties of in-medium nucleons and nucleonic systems. The mesonic sector of the model contains the nonlinear pion fields propagating in the nuclear medium. The properties of in-medium pions are defined by the pion-nucleus optical potential. The isospin-breaking part of the optical potential and the isospin-breaking effects in the mesonic sector generate the isospin-breaking effects in the baryonic sector. Further, the isospin-breaking effects in the baryonic sector are related to the asymmetric-matter properties. First, we discuss the binding energy per nucleon and the bulk properties of the isospin-symmetric nuclear matter. Then, we include the isospin-breaking effects and discuss the asymmetric-matter properties.
