Complexity Analysis of the Hydrogenic Spectrum in Strong Fieldstification and characterization of the most distinctive spectroscopic features of complex systems caused by slowly varying perturbations, the so-called avoided crossings. This is illustrated for some pairs of hydrogenic levels in presence of strong magnetic and electric fields. It is found that the

Atomic Density Functions: Atomic Physics Calculations Analyzed with Methods from Quantum Chemistryexpression for the density function for atoms in the multi-configuration Hartree–Fock scheme is established. The spherical harmonic content of the density function and ways to restore the spherical symmetry in a general open-shell case are treated. The evaluation of the density function is illustrat

Density Scaling for Excited Statesm scheme with a scaled density. It is shown that there exists a value of the scaling factor for which the correlation energy disappears. Generalized OPM and KLI methods incorporating correlation are proposed. A ζKLI method as simple as the original KLI method is presented for excited states.

Shifts in Excitation Energies Induced by Hydrogen Bonding: A Comparison of the Embedding and Supermorozen-density embedding theory (FDET), are compared with the results of the high-level equation-of-motion coupled-cluster (EOMCC) calculations with singles, doubles, and noniterative triples, which provide the reference ab initio data, the supermolecular time-dependent density functional theory (TDD

Multiparticle Distribution of Fermi Gas System in Any Dimension The results are expressed as determinant forms, in which a correlation kernel plays a vital role. The expression obtained for the one-dimensional Fermi gas is essentially equivalent to that observed for the eigenvalue distribution of random unitary matrices, and thus to that conjectured for the dis
