The atomic orbitals of the topological atom [PDF]
, 2013 The effective atomic orbitals have been realized in the framework of Bader’s atoms in molecules theory for a general wavefunction. This formalism can be used to retrieve from any type of calculation a proper set of orthonormalized numerical atomic ...

Entangled collective-spin states of atomic ensembles under non-uniform atom-light interaction [PDF]
, 2015 We consider the optical generation and verification of entanglement in atomic ensembles under non-uniform interaction between the ensemble and an optical mode. We show that for a wide range of parameters a system of non-uniformly coupled atomic spins can

$3d$-electrons contribution to cohesive energy of $3d$-metals [PDF]
, 2018 In this paper a model for $3d$-subsystem of transition $3d$-metals has been proposed and used for calculation of the cohesive energy dependent on $3d$-band filling of particular metal, its bandwidth and effective intra-atomic interaction value.

Determination of the effective atomic number: A theoretical justification
EPL (Europhysics Letters), 2018 In this paper, we have tried to seek a theoretical justification for the effective atomic number for Compton scattering studies by computing it from free atom Hartree-Fock wave function based Compton profiles compiled by Biggs et al. Typical experimental examples have been provided which show a good agreement with that of theory justifying the validity

Dopant Concentration and Effective Atomic Number of Copper-Doped Potassium Borate Glasses
Advances in Materials Science and Engineering, 2013 Copper-doped (0.5 mol%) and undoped potassium borate glasses have been prepared by the composition of (100-x)H3BO3 + xK2CO3, where 10 ≤ x ≤ 30 mol % by the traditional melting quenching method. The structural pattern of glasses with different composition
