Towards non-local density functionals by explicit modeling of the exchange-correlation hole in inhomogeneous systems
Klaas J. H. Giesbertz, Robert van Leeuwen, Ulf von Barth
We put forward new approach for the development of a non-local density functional by a direct modeling of the shape of exchange-correlation (xc) hole in inhomogeneous systems. The…
Exact Density-Functionals with Initial-State Dependence and Memory
M. Ruggenthaler, S. E. B. Nielsen, R. van Leeuwen
We analytically construct the wave function that, for a given initial state, produces a prescribed density for a quantum ring with two non-interacting particles in a singlet state.…
Density-potential mappings in quantum dynamics
M. Ruggenthaler, K. J. H Giesbertz, M. Penz +1
In a recent letter [Europhys. Lett. 95, 13001 (2011)] the question of whether the density of a time-dependent quantum system determines its external potential was reformulated as a…
Challenges in Truncating the Hierarchy of Time-Dependent Reduced Density Matrices Equations: Open Problems
Ali Akbari, Mohammad Javad Hashemi, Risto M. Nieminen +2
In this work, we analyze the Born, Bogoliubov, Green, Kirkwood and Yvon (BBGKY) hierarchy of equations for describing the full time-evolution of a many-body fermionic system in ter…
