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 ...

$3d$-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.

Atomic Parity Non-Conservation, Neutron Radii, and Effective Field Theories of Nuclei [PDF]

, 2005
Accurately calibrated effective field theories are used to compute atomic parity non-conserving (APNC) observables. Although accurately calibrated, these effective field theories predict a large spread in the neutron skin of heavy nuclei.
