Abstract
The finite temperature and finite density dependence of the neutron-pr oton mass difference is analyzed in a purely hadronic framework where the rho-omega mixing is crucial for this isospin symmetry breakdown. T he problem is handled within thermofield dynamics. The present results , consistent with partial chiral and charge symmetry restoration, impr ove the experimental data fit for the energy difference between mirror nuclei.
