QED calculation of the dipole polarizability of helium atom

Mariusz Puchalski, Krzysztof Szalewicz, Michal Lesiuk +1

The QED contribution to the dipole polarizability of the He atom was computed, including the effect of finite nuclear mass. The computationally most challenging contribution of…

Rovibrational energy levels of the hydrogen molecule through nonadiabatic perturbation theory

Jacek Komasa, Mariusz Puchalski, Paweł Czachorowski +2

We present an accurate theoretical determination of rovibrational energy levels of the hydrogen molecule and its isotopologues in its electronic ground state. We consider all signi…

The full infrared spectrum of molecular hydrogen

E. Roueff, H. Abgrall, P. Czachorowski +3

The high spectral resolution R about 45,000 provided by IGRINS (Immersion Grating INfrared Spectrometer) at MacDonald Observatory and R 100,000 achieved by CRIRES (CRyogenic high-r…

Dissociation Energy of Molecular Hydrogen Isotopologues

Mariusz Puchalski, Jacek Komasa, Anna Spyszkiewicz +1

The nonrelativistic energy together with relativistic and quantum electrodynamic corrections for all the molecular hydrogen isotopologues (D, T, HD, HT, DT) were evaluated…

Quantum electrodynamic corrections to the states of the helium atom

Albert Wienczek, Krzysztof Pachucki, Mariusz Puchalski +2

We perform quantum electrodynamic calculations of the ionization energy of the states of the He atom, including a complete evaluation of the correction. We find a…

Refractive index and generalized polarizability

Krzysztof Pachucki, Mariusz Puchalski

We investigate the role of retardation corrections to polarizability and to refractive index. We found that the classical electromagnetic theory of dielectrics requires correspondi…
