One-particle operator representation over two-particle basis sets for relativistic QED computations
Péter Hollósy, Péter Jeszenszki, Edit Mátyus
This work is concerned with two-spin-1/2-fermion relativistic quantum mechanics, and it is about the construction of one-particle projectors using an inherently two(many)-particle,…

Lower bounds on par with upper bounds for few-electron atomic energies
Miklos Ronto, Peter Jeszenszki, Edit Mátyus +1
The development of computational resources has made it possible to determine upper bounds for atomic and molecular energies with high precision. Yet, error bounds to the computed e…

Variational versus perturbative relativistic energies for small and light atomic and molecular systems
Dávid Ferenc, Péter Jeszenszki, Edit Mátyus
Variational and perturbative relativistic energies are computed and compared for two-electron atoms and molecules with low nuclear charge numbers. In general, good agreement of the…
