Density Matrix Perturbation Theory
Anders M. N. Niklasson, Matt Challacombe
An expansion method for perturbation of the zero temperature grand canonical density matrix is introduced. The method achieves quadratically convergent recursions that yield the re…

Ab initio linear scaling response theory: Electric polarizability by perturbed projection
Valery Weber, Anders Niklasson, Matt Challacombe
A linear scaling method for calculation of the static {\em ab inito} response within self-consistent field theory is developed and applied to calculation of the static electric pol…
