ELSI -- An Open Infrastructure for Electronic Structure Solvers

Victor Wen-zhe Yu, Carmen Campos, William Dawson +16

Routine applications of electronic structure theory to molecules and periodic systems need to compute the electron density from given Hamiltonian and, in case of non-orthogonal bas…

Influence of point defects on the electronic and topological properties of monolayer WTe

Lukas Muechler, Wei Hu, Chao Yang +2

In some topological insulators, such as graphene and WTe, band inversion originates from chemical bonding and space group symmetry, in contrast to materials such as BiSe$_3…

A greedy algorithm for computing eigenvalues of a symmetric matrix

Taylor M. Hernandez, Roel Van Beeumen, Mark A. Caprio +1

We present a greedy algorithm for computing selected eigenpairs of a large sparse matrix that can exploit localization features of the eigenvector. When the eigenvector to be c…

Approximate Green's Function Coupled Cluster Method Employing Effective Dimension Reduction

Bo Peng, Roel Van Beeumen, David B. Williams-Young +2

The Green's function coupled cluster (GFCC) method is a powerful many-body tool for computing the electronic structure of molecular and periodic systems, especially when electrons…
