Symmetry-adapted perturbation theory based on multiconfigurational wave function description of monomers

Michal Hapka, Michal Przybytek, Katarzyna Pernal

We present a formulation of the multiconfigurational (MC) wave function symmetry-adapted perturbation theory (SAPT). The method is applicable to noncovalent interactions between mo…

Second virial coefficients for helium-4 and helium-3 from accurate relativistic interaction potential

Paweł Czachorowski, Michał Przybytek, Michał Lesiuk +2

The second virial coefficient and the second acoustic virial coefficient for helium-4 and helium-3 are computed for a wide range of temperatures (0.5 - 1000K) using a highly accura…

Theoretical determination of polarizability and magnetic susceptibility of neon

Michał Lesiuk, Michał Przybytek, Bogumił Jeziorski

We report theoretical determination of the dipole polarizability of the neon atom, including its frequency dependence. Corrections for the relativistic, quantum electrodynamics, fi…

Second-order exchange-dispersion energy based on multireference description of monomers

Hapka Michał, Przybytek Michał, Pernal Katarzyna

We present a method for calculation of the second-order exchange-dispersion energy in the framework of the symmetry-adapted perturbation theory (SAPT) for weakly interacting monome…

Ab initio potential energy curve for the ground state of beryllium dimer

Michał Lesiuk, Michał Przybytek, Justyna G. Balcerzak +2

This work concerns \emph{ab initio} calculations of the complete potential energy curve and spectroscopic constants for the ground state of the beryllium dimer, Be.…

Dispersion energy of symmetry-adapted perturbation theory from explicitly correlated F12 approach

Michal Przybytek

Methods of the explicitly correlated F12 approach are applied to the problem of calculating the uncoupled second-order dispersion energy in symmetry-adapted perturbation theory. Th…
