    "abstract": "Density functional theory is discussed in the context of one-particle\nsystems. We show that the ground state density $\\rho_0(x)$ and energy $E_0$ are\nsimply related to a family of external potential energy functions with ground\nstate wave functions $\\psi_n(x) \\propto \\rho_0(x)^n$ and energies $E_n=2nE_0$\nfor certain integer values of $n$.",
