A state-averaged orbital-optimized hybrid quantum-classical algorithm for a democratic description of ground and excited states

Saad Yalouz, Bruno Senjean, Jakob Günther +3

In the Noisy Intermediate-Scale Quantum (NISQ) era, solving the electronic structure problem from chemistry is considered as the "killer application" for near-term quantum devices.…

Generalization of intrinsic orbitals to Kramers-paired quaternion spinors, molecular fragments and valence virtual spinors

Bruno Senjean, Souloke Sen, Michal Repisky +2

Localization of molecular orbitals finds its importance in the representation of chemical bonding (and anti-bonding) and in the local correlation treatments beyond mean-field appro…

Weight Dependence of Local Exchange-Correlation Functionals in Ensemble Density-Functional Theory: Double Excitations in Two-Electron Systems

Clotilde Marut, Bruno Senjean, Emmanuel Fromager +1

Gross--Oliveira--Kohn (GOK) ensemble density-functional theory (GOK-DFT) is a time-\textit{independent} extension of density-functional theory (DFT) which allows to compute excited…

N-centered ensemble density-functional theory for open systems

Bruno Senjean, Emmanuel Fromager

Two (so-called left and right) variants of N-centered ensemble density-functional theory (DFT) [Senjean and Fromager, Phys. Rev. A 98, 022513 (2018)] are presented. Unlike the orig…
