One-dimensional Plasmons and Hybridized Coupled Polaritons in Carbon Nanotubes
James Kestyn, Sigfrid K. Yngvesson, Eric Polizzi
This paper presents real-time time-dependent density functional theory (TDDFT) ab-initio simulations of selected armchair carbon nanotubes (CNTs). By scaling the lengths of CNTs, w…
A method of calculating bandstructure in real-space with application to all-electron and full potential
Dongming Li, James Kestyn, Eric Polizzi
We introduce a practical and efficient approach for calculating the all-electron full potential bandstructure in real space, employing a finite element basis. As an alternative to…
From Fundamental First-Principle Calculations to NanoEngineering Applications: Review of the NESSIE project
James Kestyn, Eric Polizzi
This paper outlines how modern first-principle calculations can adequately address the needs for ever higher levels of numerical accuracy and high-performance in large-scale electr…
FEAST Eigensolver for non-Hermitian Problems
James Kestyn, Eric Polizzi, Ping Tak Peter Tang
A detailed new upgrade of the FEAST eigensolver targeting non-Hermitian eigenvalue problems is presented and thoroughly discussed. It aims at broadening the class of eigenproblems…
A New Highly Parallel Non-Hermitian Eigensolver
Ping Tak Peter Tang, James Kestyn, Eric Polizzi
Calculating portions of eigenvalues and eigenvectors of matrices or matrix pencils has many applications. An approach to this calculation for Hermitian problems based on a density…
FEAST Eigenvalue Solver v3.0 User Guide
Eric Polizzi, James Kestyn
The FEAST eigensolver package is a free high-performance numerical library for solving the Hermitian and non-Hermitian eigenvalue problems, and obtaining all the eigenvalues and (r…
