Vorticity expansion approximation of the exchange-correlation energy functional in current density functional theory
We propose the vorticity expansion approximation VEA formulas of the exchange and correlation energy functionals of the current density functional theory CDFT . They have a form of the second-order expansion with respect to the vorticity. Expansion coefficients are determined by requiring them to satisfy exact relations that have been derived from scaling properties of exchange and correlation ...
متن کاملLocal approximation of the correlation energy functional in the density matrix functional theory.
A local approximation formula of the correlation energy functional E(c) in terms of the first-order reduced density matrix (1-RDM) is presented. With the contracted Schrödinger equation the principal dependence of E(c) on the natural occupation numbers n(i) is identified. Using the effective mass theory, E(c) is expressed as a functional of the local density and the local variable, J = SUM (i)[...
متن کاملCalculating excited state properties using Kohn-Sham density functional theory.
The accuracy of excited states calculated with Kohn-Sham density functional theory using the maximum overlap method has been assessed for the calculation of adiabatic excitation energies, excited state structures, and excited state harmonic and anharmonic vibrational frequencies for open-shell singlet excited states. The computed Kohn-Sham adiabatic excitation energies are improved significantl...
متن کاملAccounting for spin fluctuations beyond local spin density approximation in the density functional theory
We present a method to correct the magnetic properties of itinerant systems in the local-spin-density approximation (LSDA), and we apply it to the ferromagnetic-paramagnetic transition under pressure in a typical itinerant system Ni3Al. We obtain a scaling of the critical fluctuations as a function of pressure equivalent to the one obtained within Moryia’s theory. Moreover, we show that in this...
متن کاملQuantal density functional theory of excited states.
We explain by quantal density functional theory the physics of mapping from any bound nondegenerate excited state of Schrödinger theory to an S system of noninteracting fermions with equivalent density and energy. The S system may be in a ground or excited state. In either case, the highest occupied eigenvalue is the negative of the ionization potential. We demonstrate this physics with example...
