Implicit density-functional theory [PDF]
Physical Review A, 2006 A fermion ground state energy functional is set up in terms of particle density, relative pair density, and kinetic energy tensor density. It satisfies a minimum principle if constrained by a complete set of compatibility conditions. A partial set, which thereby results in a lower bound energy under minimization, is obtained from the solution of model ...

Spin in density‐functional theory [PDF]
International Journal of Quantum Chemistry, 2012 AbstractThe accurate description of open‐shell molecules, in particular of transition metal complexes and clusters, is still an important challenge for quantum chemistry. Although density‐functional theory (DFT) is widely applied in this area, the sometimes severe limitations of its currently available approximate realizations often preclude its ...

Current densities in density-functional theory [PDF]
Physical Review A, 2013 It is well known that any given density rho(x)can be realized by a determinantal wave function for N particles. The question addressed here is whether any given density rho(x) and current density j(x) can be simultaneously realized by a (finite kinetic energy) determinantal wave function.
