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…
