Generalization of the density-matrix method to a non-orthogonal basis
R. W. Nunes, David Vanderbilt
We present a generalization of the Li, Nunes and Vanderbilt density-matrix method to the case of a non-orthogonal set of basis functions. A representation of the real-space density…

Real-space approach to calculation of electric polarization and dielectric constants
R. W. Nunes, David Vanderbilt
We describe a real-space approach to the calculation of the properties of an insulating crystal in an applied electric field, based on the iterative determination of the Wannier fu…
