Abstract：
Recent works on the relativistic description of exotic nuclei and nuclear matter at extreme conditions are reviewed. New effective interactions, PK1, PK1r and PKDD in the relativistic mean field(RMF)theory, are proposed with the center-of-mass correction included in a microscopic way. They are able to provide an excellent description not only for the properties of nuclear matter and neutron stars, but also for the nuclei near or far from the beta–stability line, including halos and giant halos at the neutron drip line in nuclei and hyper–nuclei. Based on the solution of the RMF equations, good spin symmetry is found in anti–nucleon spectra.
