code for manipulating FSRCC effective Hamiltonian eigenstates

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) or EXP-T code.
