Adaptive Finite Differencing in High Accuracy Electronic Structure Calculations
E. L. Briggs, Wenchang Lu, J. Bernholc
A new method for implementing the kinetic energy operator for real-space, grid-based electronic structure codes is developed. It is based on multi-order Adaptive Finite Differencin…
Local manifestations of thickness dependent topology and axion edge state in topological magnet MnBiTe
Felix Lüpke, Anh D. Pham, Yi-Fan Zhao +9
The interplay of non-trivial band topology and magnetism gives rise to a series of exotic quantum phenomena, such as the emergent quantum anomalous Hall (QAH) effect and topologica…
Parallel implementation of electronic structure eigensolver using a partitioned folded spectrum method
E. L. Briggs, C. T. Kelley, J. Bernholc
A parallel implementation of an eigensolver designed for electronic structure calculations is presented. The method is applicable to computational tasks that solve a sequence of ei…
Multigrid Methods in Electronic Structure Calculations
E. L. Briggs, D. J. Sullivan, J. Bernholc
We describe a set of techniques for performing large scale ab initio calculations using multigrid accelerations and a real-space grid as a basis. The multigrid methods provide effe…
Large Scale Electronic Structure Calculations with Multigrid Acceleration
E. L. Briggs, D. J. Sullivan, J. Bernholc
We have developed a set of techniques for performing large scale ab initio calculations using multigrid accelerations and a real-space grid as a basis. The multigrid methods permit…
