- theory of effective operators
- relativistic quantum chemistry
- theoretical chemistry of superheavy elements

- multireference relativistic coupled cluster theory
- first-principle based modeling of superheavy element properties
- theoretical chemistry of early transuranium elements

The code is designed to perform

- finite-field transition dipole moment calculations (A.V. Zaitsevskii, L.V. Skripnikov, A.V. Kudrin, A.V. Oleinichenko, E. Eliav, A.V. Stolyarov, Optics and Spectroscopy, 124, 4, 451-456 (2018))
- quasidiabatization by projection ( A. Zaitsevskii, N.S. Mosyagin, A.V. Stolyarov, E. Eliav, Phys. Rev. A, 96, 022516 (2017))
- Pade extrapolation of effective Hamiltonians (A. Zaitsevskii, E. Eliav. Int. J. Quantum Chem. 118 (23), e25772 (2018))

It is supposed that the effective Hamiltonians are obtained using Fock space relativistic coupled cluster facility of DIRAC, a relativistic ab initio electronic structure program (release DIRAC17 or later).
