The finite temperature and finite density dependence of the neutron-protonmass difference is analysed in a purely hadronic framework where the$\rho-\omega $ mixing is crucial for this isospin symmetry breakdown. Theproblem is handled within Thermo Field Dynamics. The present results,consistent with partial chiral and charge symmetry restoration, improve theexperimental data fit for the energy difference between mirror nuclei.Comment: 17 pages, revtex fil
