Compressed Representation of Kohn−Sham Orbitals via Selected Columns of the Density Matrix
Compressed Representation Kohn− Sham Orbitals Selected Columns Density Matrix
2015/7/14
Given a set of Kohn−Sham orbitals from an insulating system, we present a simple, robust, efficient, and highly parallelizable method to construct a set of optionally orthogonal, localized basis...
Applications of density matrix in the fractional quantum mechanics
Applications of density matrix fractional quantum mechanics
2011/2/25
The many-body space fractional quantum system is studied using the density matrix method. We give the new results of the Thomas-Fermi model, and obtain the quantum pressure of the free electron gas. W...

On the relationship between parametric two-electron reduced-density-matrix methods coupled electron pair approximation
2010/12/15
Parametric two-electron reduced-density-matrix (p-2RDM) methods have enjoyed much success
in recent years; the methods have been shown to exhibit accuracies greater than coupled cluster
with single ...
