Rovibrational computations for the He a state including non-adiabatic, relativistic, and QED corrections
Ãdám Margócsy, Balázs Rácsai, Péter Jeszenszki +1
A potential energy curve (PEC) accurate to a fraction of 1 ppm () is computed for the state of He endowed with relativistic and QED corrections. The…
Double-pair Coulomb and Breit photon correction to the correlated relativistic energy
Péter Jeszenszki, Edit Mátyus
The simplest, algebraic quantum-electrodynamical corrections, due to the double-negative energy subspace and instantaneous interactions, are computed to the no-pair energy of two-s…
High-Precision Quantum Dynamics of He over the b -c Electronic Subspace by including Non-adiabatic, Relativistic and QED Corrections and Couplings
Balázs Rácsai, Péter Jeszenszki, Ãdám Margócsy +1
Relativistic, quantum electrodynamics, as well as non-adiabatic corrections and couplings, are computed for the b and c electronic states of t…
Spin-dependent terms of the Breit-Pauli Hamiltonian evaluated with an explicitly correlated Gaussian basis set for molecular computations
Péter Jeszenszki, Péter Hollósy, Ãdám Margócsy +1
This work collects the spin-dependent leading-order relativistic and quantum-electrodynamical corrections for the electronic structure of atoms and molecules within the non-relativ…
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,…
