Model selection in atomistic simulation
Jonathan E. Moussa
There are many atomistic simulation methods with very different costs, accuracies, transferabilities, and numbers of empirical parameters. I show how statistical model selection ca…
Accurate Frozen Core Approximation for All-Electron Density-Functional Theory
Victor Wen-zhe Yu, Jonathan Moussa, Volker Blum
We implement and benchmark the frozen core approximation, a technique commonly adopted in electronic structure theory to reduce the computational cost by means of mathematically fi…
Real time evolution for ultracompact Hamiltonian eigenstates on quantum hardware
Katherine Klymko, Carlos Mejuto-Zaera, Stephen J. Cotton +9
In this work we present a detailed analysis of variational quantum phase estimation (VQPE), a method based on real-time evolution for ground and excited state estimation on near-te…
Robust decompositions of quantum states
Jonathan E. Moussa
Classical-quantum computational complexity separations are an important motivation for the long-term development of digital quantum computers, but classical-quantum complexity equi…
GPU-Acceleration of the ELPA2 Distributed Eigensolver for Dense Symmetric and Hermitian Eigenproblems
Victor Wen-zhe Yu, Jonathan Moussa, Pavel Kůs +5
The solution of eigenproblems is often a key computational bottleneck that limits the tractable system size of numerical algorithms, among them electronic structure theory in chemi…
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…
