Failure of Density-matrix Minimization Methods for Linear-scaling Density-functional Theory Using the Kohn Penalty-functional
We examine the recently-proposed scheme W. Kohn, Phys. Rev. Lett. 76, 3168 (1996)] for performing linear-scaling calculations within density-functional theory by direct minimization with respect to the single-particle density-matrix using a penalty-functional to exactly enforce the idempotency constraint. We show that such methods are incompatible with standard minimization algorithms (using co...
متن کاملSelf-consistent field theory based molecular dynamics with linear system-size scaling.
We present an improved field-theoretic approach to the grand-canonical potential suitable for linear scaling molecular dynamics simulations using forces from self-consistent electronic structure calculations. It is based on an exact decomposition of the grand canonical potential for independent fermions and does neither rely on the ability to localize the orbitals nor that the Hamilton operator...
متن کاملSelf-consistent scaling theory for logarithmic-correction exponents.
Multiplicative logarithmic corrections frequently characterize critical behavior in statistical physics. Here, a recently proposed theory relating the exponents of such terms is extended to account for circumstances which often occur when the leading specific-heat critical exponent vanishes. Also, the theory is widened to encompass the correlation function. The new relations are then confronted...
متن کاملBenchmarking a Self-Consistent Field Theory for Small Amphiphilic Molecules
A minimalist self-consistent field theory for small amphiphilic molecules is presented. The equations for this model are less involved than those for block copolymers and are easily implemented computationally. A new convergence technique based on a variant of Anderson mixing is also presented which allows the equations to be solved more rapidly than block copolymer self-consistent field theory...
متن کاملStochastic Multiconfigurational Self-Consistent Field Theory.
The multiconfigurational self-consistent field theory is considered the standard starting point for almost all multireference approaches required for strongly correlated molecular problems. The limitation of the approach is generally given by the number of strongly correlated orbitals in the molecule, since its cost will grow exponentially with this number. We present a new multiconfigurational...
