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…
Potential energy curve for the state of lithium dimer with Slater-type orbitals
Michał Lesiuk, Monika Musiał, Robert Moszynski
We report state-of-the-art ab initio calculations of the potential energy curve for the state of the lithium dimer conducted to achieve spectroscopic accuracy (1cm$^{…
Implementation of the full CCSDT electronic structure model with tensor decompositions
Michał Lesiuk
We report a complete implementation of the coupled-cluster method with single, double, and triple excitations (CCSDT) where tensor decompositions are used to reduce its scaling and…
A straightforward a posteriori method for reduction of density-fitting error in coupled-cluster calculations
Michał Lesiuk
We present a simple method for \emph{a posteriori} removal of a significant fraction of the density-fitting error from the calculated total coupled-cluster energies. The method tre…
Theoretical description of the ionization processes with a discrete basis set representation of the electronic continuum
Mateusz S. Szczygieł, Michał Lesiuk, Robert Moszynski
In this work we present a new method of approximating the continuum wavefunctions with a discrete basis set. This method aims to be at least compatible with other well known method…
Complete basis set extrapolation of electronic correlation energies using the Riemann zeta function
Michał Lesiuk, Bogumił Jeziorski
In this communication we present a method of complete basis set (CBS) extrapolation of correlation energies obtained with a systematic sequence of one-electron basis sets. Instead…
