Excitation energies from ground-state density-functionals by means of generator coordinates
E. Orestes, A. B. F. da Silva, K. Capelle
The generator-coordinate method is a flexible and powerful reformulation of the variational principle. Here we show that by introducing a generator coordinate in the Kohn-Sham equa…

The generator coordinate method in time-dependent density-functional theory: memory made simple
E. Orestes, K. Capelle, A. B. F. da Silva +1
The generator coordinate (GC) method is a variational approach to the quantum many-body problem in which interacting many-body wave functions are constructed as superpositions of (…

Density-functional calculation of ionization energies of current-carrying atomic states
E. Orestes, T. Marcasso, K. Capelle
Current-density-functional theory is used to calculate ionization energies of current-carrying atomic states. A perturbative approximation to full current-density-functional theory…
