    "abstract": "The density-functional (DF) theory provides a simple method for calculating\nthe properties of an interacting system under an external potential by\nassociating it with a corresponding non-interacting system. Here, we find some\nrelations in this non-interacting system, which can enable us to set up the\nthermodynamical relations for a neutral electron-nucleus mixture in terms of\nquantities of the non-interacting system and the exchange-correlation effect.\nIn this way, Andersen\u0027s force theorems are clearly described and easily proved\nin conjunction with other types of force theorems, Janak\u0027s theorem extended to\na finite-temperature system, pressure formulas and some thermodynamical\nrelations. For this purpose, the thermodynamics in the DF theory is presented\nin a systematic and explicit way.",
